OPINION ON STATE’S PETITION FOR DISCRETIONARY REVIEW
Appellant was convicted of the offense of aggravated sexual abuse of a child. Punishment, enhanced by two prior convictions was assessed at life imprisonment.
Appellant was charged with sexually abusing a seven-year-old child. At trial, appellant argued the affirmative defense of insanity. V.T.C.A., Penal Code, Section 8.01. 1 Appellant’s sole defense witness was Dr. Collier Cole, a clinical psychologist who testified that, in his opinion, appellant was a pedophiliac and could not conform his conduct to the requirements of the law. The State presented no expert witnesses. In its charge to the jury, the trial court instructed the jury on the affirmative defense of insanity. Immediately after applying the law of insanity to the facts of the case, over the appellant’s objection, the trial court gave the following instruction:
“You are instructed that you are not bound by the testimony offered by a witness qualified as an expert. You may give it the weight to which you find it is entitled and may weigh such testimony with all other evidence offered in this case.”
Later in the charge, the court gave the following instruction:
“You are the exclusive judges of the facts proved, the credibility of the witnesses, and of the weight to be given to their testimony, but you are bound to receive the law from the Court which is herein given to you and be governed thereby.”

On original appeal, the Court of Appeals held that the instruction concerning the expert witness was a comment on the weight of the evidence in violation of Article 36.14, V.A.C.C.P. Applying the test set out in
Almanza v. State,
It is axiomatic that it is improper for a trial court to single out certain testimony and comment on it.
Chambers v. State,
It has long been held that it is reversible error for the trial court to give instructions that refer to the credibility of the witnesses. For example, in
Taylor v. State,
Certainly a comment on the weight of the evidence occurs when the judge appraises the credibility of a particular witness. Thus when a judge, in his charge to the jury, suggests that certain evidence is true or is untrue, that is a comment on the weight of the evidence.
Tew v. State,
Likewise an instruction which instructs a jury on the weight to' be given certain testimony is error. In
Marta v. State,
This Court has even held that when a defendant requests an instruction similar to the one given in the instant case, that it is proper for the trial court to refuse such an instruction because it constitutes a comment on the weight of the evidence. In
Florio v. State,
In
Clark v. State,
“The evidence of witnesses who are put on the stand to support a theory by their opinions, however expert, is justly exposed to your reasonable suspicion. Experts and witnesses are produced not to swear to a fact observed by them but to express their opinions. The value of expert opinion does not depend on the skill and the knowledge professed by the expert, but on the weight you give the kind of skill and knowledge demonstrated to you.”
The trial court refused to so instruct the jury and his ruling was upheld on appeal because the requested charge was obviously a comment on the weight of the evidence.
In
Simmons v. State,
The State correctly cites
Collins v. State,
The Texas Supreme Court faced a similar situation in
Davidson v. Wallingford,

*80
Tex. 619,
“The court should simply have charged that the jury were the judges of the credibility of the witnesses and the weight of the evidence. The effect of the instruction was to lead the jury to believe that there was more question as to the credibility of the witness who was named than as to that of the other witnesses. Whether such was the fact or not was a matter solely for the determination of the jury, without any intimation, either direct or indirect, as to the opinion of the judge.”32 S.W. at 1033 .
We find that the complained-of instruction had the same effect in the instant case. The probable effect of the instruction was to lead the jury to believe that there was more question as to the credibility of Dr. Cole, the sole expert witness and the sole defense witness, than as to that of the other witnesses. Thus the neutral instruction when taken in the context in which it was given was very capable of being construed by the jury as some kind of indirect standard for weighing the evidence endorsed by the trial court. Given the context in which the charge was given, we are compelled to agree with the Court of Appeals that the giving of the charge was improper. The State’s ground of review is overruled. 2
The judgment of the Court of Appeals is affirmed.
Notes
. At the time of appellant’s trial, V.T.C.A., Penal Code, Section 8.01(a) provided: “It is an affirmative defense to prosecution that, at the time of the conduct charged, the actor, as a result of mental disease or defect, either did not know that his conduct was wrong or was incapable of conforming his conduct to the requirements of the law he allegedly violated."
. Because we did not grant review of the State s petition as to the second ground for review, we do not reach the question of whether the Court of Appeals correctly applied the second prong of Almanza, in finding that appellant was harmed by the instruction.
