This appeal arises from an order by a juvenile court denying Doe’s motion to dismiss the State’s petition for a probation violation for lack of jurisdiction. Doe appeals the district court’s decision affirming the magistrate’s order. We reverse.
I. FACTUAL AND PROCEDURAL BACKGROUND
When he was seventeen years old, Doe was charged under the Juvenile Corrections Act (J.C.A.) and admitted to committing battery of an unspecified sexual nature. He was placed on intensive probation on August 13, 2003. On June 6, 2006, the magistrate amended the order of probation, ordering formal probation for a period not to exceed Doe’s twenty-first birthday. The conditions of Doe’s probation prohibited him from having contact with sexually explicit material or pornography and contact with alcohol.
On October 4, 2006, Doe admitted to his probation officer that on September 26, 2006, while at his mother’s house, he looked at pornography on the internet and consumed alcohol. On October 13, 2006, the State filed a petition alleging that Doe had violated the terms of his probation. Doe turned twenty-one on November 4, 2006. On November 14, 2006, the magistrate court issued a summons ordering Doe to appear for an admit/deny hearing. On November 20, 2006, Doe appeared at the hearing and denied the allegations of probation violation.
On January 19, 2007, Doe filed a motion to dismiss the petition, arguing that I.C. § 20-507 terminated the court’s jurisdiction when he turned twenty-one years of age. At a January 31, 2007 hearing, the magistrate orally denied Doe’s motion to dismiss, and on March 19, 2007, the magistrate issued a written order denying Doe’s motion to dismiss. On February 5, 2007, Doe moved for permission to appeal the order denying his motion to dismiss. On March 19, 2007, the magistrate entered an order permitting Doe to appeal. Doe filed his notice of appeal that same day. On September 4, 2007, the district court affirmed the decision of the magistrate court. Doe timely appealed to this Court.
II. STANDARD OF REVIEW
When reviewing a decision of the district court acting in its appellate capacity, this Court reviews the trial court’s record to determine whether there is substantial and competent evidence to support the magistrate’s findings of fact and whether the magistrate’s conclusions of law follow from those findings.

Carrier v. Lake Pend Oreille Sch. Dist. No. 84,
III. ANALYSIS
By operation of I.C. § 20-505, the trial court had “exclusive, original jurisdiction” over Doe when he was charged with committing a battery while under the age of eighteen. I.C. § 20-505(2). Neither party contests the juvenile court’s jurisdiction over Doe while he was a minor; rather, the parties disagree whether the juvenile court’s jurisdiction over Doe terminated when he turned twenty-one years of age by operation of I.C. § 20-507.
Idaho Code § 20-507 provides, in pertinent part, that “[jurisdiction obtained by the court in the case of a juvenile shall be retained by it for the purposes of this act until he becomes twenty-one (21) years of age, unless terminated prior thereto.” Based upon this provision, Doe asserts that the juvenile court’s jurisdiction terminated when he became twenty-one and thus, the petition for probation violation must be dismissed.
The State responds that this case should be decided by analogy to the reasoning in
State v. Harvey,
In Harvey, the Court of Appeals considered the case of a probationer who appeared determined not to submit to supervision. In 1986, following a period of retained jurisdiction, Harvey was placed on probation. For purposes of analysis, the Court of Appeals applied the version of I.C. § 20-222 in effect at the time of Harvey’s original sentencing. This statute provided that the maximum period of probation, including extensions, was five years. 1 In September 1989, the district court issued a warrant for Harvey’s arrest based upon the State’s petition alleging probation violations. Harvey was arrested in another state in December 1989. After Harvey admitted violating the terms of probation, the district court continued probation and ordered Harvey to serve ninety days in *329 jail. In March 1990, the district court issued another warrant upon the State’s petition alleging that Harvey had violated probation by escaping from jail. Harvey was arrested out of state in October 1991. In December 1991, Harvey was again placed on probation. In March 1992, the district court issued another warrant following the State’s third petition for probation violation. Harvey was not arrested until April 1997, when he was again found in another state. This time the district court revoked Harvey’s probation and in June 1997 the court ordered Harvey to serve a twenty year prison term, with five years fixed.
In 2002, Harvey filed an I.C.R. 35 motion to correct an illegal sentence. He argued that when the district court revoked his probation, it lacked jurisdiction to do so. Interpreting I.C. § 20-222, the Court of Appeals determined that a probationary period is tolled “from the date probation revocation proceedings are commenced until probation is continued or revoked.”
The
Harvey
decision reflects one salient fact: I.C. § 20-222 does not contain language that explicitly defines the duration of the trial court’s jurisdiction. Thus, the Court of Appeals appropriately fulfilled its “duty to ascertain the legislative intent and give effect to that intent.”
Id.
at 730,
Although there is superficial appeal in the State’s invitation to apply Harvey because the State filed the petition prior to the termination of Doe’s probation, this approach is inconsistent with our approach to statutory interpretation. As previously observed, our interpretation of a statute begins with the literal words of the statute. Idaho Code § 20-507 provides that the juvenile court’s jurisdiction “shall be retained by it for the purposes of this act until he becomes twenty-one (21) years of age, unless terminated prior thereto.” The plain language of the statute indicates that a juvenile court ceases to retain jurisdiction, i.e., jurisdiction is terminated, once the juvenile reaches twenty-one years of age.
The State argues that Doe’s interpretation of I.C. § 20-507 is inconsistent with other provisions of the J.C.A. that permit the juvenile court to exercise jurisdiction over adults, those over the age of eighteen. I.C. § 20-502(1). Specifically, the State argues that Doe’s interpretation of I.C. § 20-507 is inconsistent with I.C. §§ 20 — 508(l)(c), 20-508(1)(d), and 20-508(9). The first two provisions relate to the waiver of the exclusive, original jurisdiction of the juvenile court and the latter relates to the transfer of cases to courts in the offenders’ home counties. The use of the word “adult” in these provisions is not inconsistent with the operation of I.C. § 20-507 to terminate the jurisdiction of a juvenile court once the adult reaches twenty-one years of age. This Court harmoniously construes statutes relating to the same subject whenever possible.
Edwards v. Indus. Comm’n of State,
Finally, the State argues that Doe’s interpretation of I.C. § 20-507 leads to an absurd result because Doe will go unpunished for any violation of the terms of his probation. While it is true that Doe will escape punishment for his alleged probation violation, this is a policy consideration we are unable to consider in the instant case. The language of the statute is unambiguous. We are not free to rewrite a statute under the guise of statutory construction.
State v. Lindquist,
*330
We conclude that under the plain language of I.C. § 20-507, the juvenile court’s jurisdiction terminated when Doe reached twenty-one years of age. This conclusion is consistent with that reached by another supreme court addressing a similar issue. In the case
In re Jaime P.,
IV. CONCLUSION
By operation of I.C. § 20-507, the juvenile court’s jurisdiction terminated when Doe reached twenty-one years of age. We reverse the district court’s decision affirming the magistrate’s order denying Doe’s motion to dismiss.
Notes
. The 1986 Legislature amended I.C. § 20-222 to its current form. See 1986 Idaho Sess. Laws, ch. 311, § 1. The statute now provides that the period of probation shall not exceed the maximum period for which the defendant might have been imprisoned.
