Teleioo, the verb behind "made perfect through sufferings" in Hebrews 2:10, derives from the adjective teleios. It does not mean "without flaw," though "perfect" is an adequate translation. Its meaning is practical, not abstract or philosophical: to accomplish, consummate, or bring something to the state of being fit for its intended purpose. Old Testament sacrificial animals were called perfect because they suited their use, even if they had hidden defects. Teleios can also mean mature, and a mature person is not thereby flawless. Even someone newly baptized is called perfect. A welder's jig, adapted to hold a piece in place, is "perfect for the job," and that is the sense here. Christ, the archegos (author, captain, pioneer, trailblazer) of salvation, was made perfect through suffering so that He could carry out His work as Savior and High Priest. He is also the prodromos, the forerunner who scouted the way into God's presence. God likewise uses suffering to make His people perfectly adapted for working under Christ in the Kingdom. Like Paul, they may see themselves as wretched, yet God can make them perfect for the responsibility He intends, with character first of all. Suffering has no value in itself, but suffering for righteousness' sake prepares them to rule, serve, and bear with others' offenses as Christ did.

In the New Testament, the adjective teleios does not mean abstract, metaphysical, or philosophical perfection. It describes a thing or person that fulfills its intended purpose, as with an unblemished sacrificial animal, a mature scholar past the elementary stage, a full-grown human being, or a baptized Christian. The verb teleioun therefore means not so much "to make perfect" as "to make fully adequate for the task for which it is intended." In Hebrews 2:10, God made Jesus, the archegos (Captain, Author, Pioneer) of salvation, perfect through sufferings, which means suffering fully equipped Him for that role. Through suffering He identified with humanity, sharing flesh and blood and facing temptation, since real sympathy requires having experienced what another has endured. Having been made perfect through suffering and having learned obedience, He is now a merciful and faithful High Priest who can aid those who are tempted. He blazed the trail to God for us to follow. His aid does not replace our effort but blends with it, as in Philippians 2:12-13 and 4:13, where Paul does all things while Christ strengthens him. In the same way, Christ's strength is made perfect in weakness (II Corinthians 12:9), so that His sufficient grace enables us to continue in our trials.

The Greek verb *teleioo* (G5048), derived from the adjective *teleios*, carries a distinct meaning in the New Testament, focusing on fulfillment of purpose rather than abstract perfection. It describes something or someone fully equipped for their intended role. For instance, it applies to an unblemished animal fit for sacrifice, a mature scholar beyond elementary learning, a full-grown human or animal, or a baptized Christian. The essence of *teleios* is the complete realization of design or purpose. Thus, *teleioo* means to make fully adequate for a specific task, not merely to perfect in a general sense. In Hebrews 2:10, this concept is applied to Jesus Christ, where through suffering, He was made fully adequate as the Captain, Author, and Pioneer of our salvation. His sufferings enabled Him to identify with humanity, ensuring He could lead as the *archegos* and sympathize with human struggles. This process of being made complete through suffering equipped Him to aid those who are tempted, providing the necessary help and strength for their battles, while still requiring their active participation.
