delivered the opinion of the Court.
Mоre than twenty years have elapsed since this Court last examined the use of an alibi as a defense in a criminal cause and the nature of the burden of proof when an alibi is relied upon. In light of the apparent confusion which surrounds the use of this defense, particularly with respect to instructing the jury, we now address this area once again.
John Joseph Grady, the respondent, was convicted in the Circuit Court for Prince George’s County by a jury (Robert B.-Mathias, J., presiding) of committing unnatural and perverted sexual praсtices as well as assault and battery upon three young children. After Judge Mathias suspended the prison sentence he imposed and placed the respondent on five years supervised probation, Grady appealed to the Court of Special Appeals. That court, while also finding two other grounds for reversal, concluded that an improper jury instruction pertaining to an alibi was sufficient to dispose of the appeal and accordingly confined its discussion to that issue.

Grady v. State,
The record discloses that two families, the Gradys and the Coads, were nеxt-door neighbors for approximately three years prior to respondent’s indictment, during which time a close friendship developed between them. Members of the Goad family, particularly Mrs. Coad and her seven-year-old daughter Kelly, often visited the Grady hоme. Frequently on these occasions Kelly was accompanied by her playmates, Meghan McGarvey, age 9, and Maureen McGarvey, age 6. On June 19, 1973, the father of Maureen and Meghan, claiming to have knowledge of improper conduct on thе part of Mr. Grady involving the three young girls, made the complaint that ultimately led to the indictment filed in this case. Although the indictment stated that the offenses occurred on or about June 19, 1973, substantial uncertainty exists as to when, how often, where, and with whom the alleged unnatural and perverted sex acts were performed. At the trial none of the girls indicated precisely when the purported acts occurred and, moreover, the State’s Attorney conceded that they could not do so. The respondent categorically denied any wrongdoing and, in an attempt to account for his activities and whereabouts during the week preceding June 20, testified that he was at work during the day and, as usual, attended classes at Georgetown University three nights that week. In addition, seeking to fill the remaining time gaps, both Grady and his wife testified with regard to other specific activities engaged in by the respondent on June 18 and 19.
At trial, Judge Mathias instructed the jury as to the alibi defense in these words:
“Now, there is evidence in this case, or been offered in this case, оr introduced, the defendant was not present at the time and the place where the offenses allegedly were committed. This may be referred to as a defense of alibi. The Court tells you that a defense of alibi is a legitimate, legal and propеr defense. The defendant may not be *181 convicted of the offense with which he is charged unless the government proves beyond a reasonable doubt that the defendant was present at the time when, and at the place where, the offenses were committed.
“If, after a full and fair consideration of all the facts and circumstances in evidence, you find that the government has failed to prove beyond a reasonable doubt that the defendant was present at the time when, and the place wherе, the offense charged was allegedly committed, you must find the defendant not guilty.
“With reference to alibi, a defendant may be entitled to acquittal if you believe the alibi testimony as his not being present at a time and place of the alleged offense, by taking into consideration this testimony with all the other evidence raising a reasonable doubt of guilt, but in order to prove an alibi conclusively, the testimony must cover the whole time in which the crime by any possibility might have been committed, and it should be subjected to rigid scrutiny.” (Emphasis added.)
The Court of Special Appeals concluded that the trial judge committed reversible error by including the segment italicized above in his instruction because in doing so he placed a burden of proof upon the defendant-respondent not permitted by law. 2 Grady v. State, supra at 91-93.
That it is incumbent upon the State to prove a defendant’s guilt, and to do so beyond a reasonable doubt, is well-established by the many decisions of this Court.
See, e.g., Wilson v. State,
Although it seems that some confusion has arisen in a few
*183
of the trial courts of this State as to the burden of proof in criminal сases in which evidence of an alibi is introduced, apparently because of certain language in
Floyd v. State,
“An alibi of an acсused, proceeding as it does upon the idea that he was elsewhere at the time of the commission of the crime, does, of course, if thoroughly established, preclude the possibility of guilt. But all the evidence in a criminal case is to be considerеd together, and the jury are not to weigh merely the evidence relating to the alibi and determine from that alone whether they have a reasonable doubt of guilt. To warrant a conviction in a criminal case the charge must be proved beyond a reasonable doubt. Wood v. State,192 Md. 643 , 649,65 A. 2d 316 [(1949)]. If the jury, considering all the evidence, inculpatory and exculpatory, entertain a reasonable doubt of the defendant’s participation in the crime, they should acquit him. Thus a defendant is entitled to acquittal if the alibi testimony, taken intо consideration with all the other evidence in the case, raises a reasonable doubt of guilt. But in order to prove an alibi conclusively, the testimony must cover the whole time in which the crime by any possibility might have been committed, and it should be subjected to rigid scrutiny.”205 Md. at 581 (emphasis added). See Shipley v. State,220 Md. 463 , 468,154 A. 2d 708 (1959); Basoff v. State,208 Md. 643 , 655,119 A. 2d 917 (1956).
The source of the confusion appears to be the italicized portion of the above quoted paragraph from Floyd. Some trial courts and members of the bar seemingly have construed that segment to mean that the defendant had the burden of establishing his alibi, either by a preponderance of the evidence or conclusively. This, however, is an erroneous *184 interpretation since that part of Floyd merely refers to the fact that to be complete an alibi must cover the entire period of time in which the offense allegеdly occurred.
Though this Court has not had an opportunity to examine this issue since
Floyd,
recently the Court of Special Appeals in a trilogy of cases,
Daniels v. State,
“We think the sound view to be that an alibi is not an affirmative defense, placing any burden upon a defendant beyond the self-evident one of attempting to erode the State’s proof to a point where it no longer convinces the fact finder beyond a reasonable doubt. Proof of an alibi, like any other defense testimony, is simply a means of controverting the State’s effort to establish criminal agency.”20 Md. App. at 459 .
Our view that it is incorrect to conceptualize an alibi as an affirmative defense with the burden of proving it resting on the accused is in accord with the decisions of the overwhelming majority of jurisdictions which have ruled on the issue.

Bennett,
Turning to the jury instructions in this case, we make the threshold observation that they must be viewed as a whole and that portions should not be read out of their proper context.
State v. Foster,
Finally, since the lаnguage which was misleading in this case was taken almost verbatim from our opinion in
Floyd v. State,
Judgment of the Court of Special Appeals affirmed.
Costs to be paid by Prince George’s County.
Notes
. In addition to finding reversible error in the alibi instruction, the court agreed with, but did not discuss, respondent’s contention that a hearsay statement by оne of the prosecution’s witnesses was improperly received in evidence and that he was denied due process because of ambiguity surrounding the time of the alleged criminal acts. Grady v. State,
. Although Grady did not object to the jury instruction, the Court of Spеcial Appeals took cognizance of the error pursuant to the plain error provision of Maryland Rule 756 g. Grady v. State, supra at 93. The State has raised no objection to this utilization of that Rule.
. Although an increasing number of states by legislation have required а defendant in a criminal case to disclose to the prosecution before trial his
*185
intention to rely on an alibi, Maryland has no comparable enactment. Such statutes, so long as they grant reciprocal rights of disclosure to the defendant, have withstood constitutional challenge.
