20:28

Pay attention to: Or “Keep watch over.” The sheep in Jehovah’s flock are dear to him because he purchased them with the precious “blood of his own Son.” Jehovah could not have paid a higher price. Humble overseers, therefore, keep watch over the welfare of each member of the flock, bearing in mind how much Jehovah loves his sheep.​—1Pe 5:1-3.

overseers: The Greek word for overseer, e·piʹsko·pos, is related to the verb e·pi·sko·peʹo, meaning “carefully watch” (Heb 12:15), and to the noun e·pi·sko·peʹ, meaning “inspection” (Lu 19:44, Kingdom Interlinear; 1Pe 2:12), “to be an overseer” (1Ti 3:1), or “office of oversight” (Ac 1:20). Therefore, the overseer was one who visited, inspected, and directed members of the congregation. Protective supervision is a basic idea inherent in the Greek term. Overseers in the Christian congregation have the responsibility to care for spiritual concerns of their fellow believers. Paul here used the term “overseers” when speaking to the “elders” from the congregation in Ephesus. (Ac 20:17) And in his letter to Titus, he uses the term “overseer” when describing the qualifications for “elders” in the Christian congregation. (Tit 1:5, 7) The terms, therefore, refer to the same position, pre·sbyʹte·ros indicating the mature qualities of the one so appointed and e·piʹsko·pos indicating the duties inherent in the appointment. This account about Paul meeting with the elders from Ephesus clearly shows that there were several overseers in that congregation. There was no set number of overseers for any one congregation, but the number serving depended on the number of those qualifying as “elders,” or spiritually mature men, in that congregation. Likewise, in writing to the Philippian Christians, Paul referred to the “overseers” there (Php 1:1), indicating that they served as a body, overseeing the affairs of that congregation.​—See study note on Ac 1:20.

God: Some ancient manuscripts read “the Lord” here, but the main text reading “God” has strong manuscript support and is viewed by many scholars as the original reading.

with the blood of his own Son: Lit., “through the blood of the own (one).” Grammatically, the Greek expression could be translated “with the blood of his own” or “with his own blood,” so the context has to be taken into consideration. In Greek, the expression ho iʹdi·os (“his own”) could stand alone without a clarifying noun or pronoun, as seen by how it is rendered at Joh 1:11 (“his own home”); at Joh 13:1 (“his own”); at Ac 4:23 (“their own people”); and at Ac 24:23 (“his people”). In non-Biblical Greek papyri, the phrase is used as a term of endearment to refer to close relatives. A reader of this verse would logically understand from the context that a noun in the singular number is implied after the expression “his own” and that the noun referred to God’s only-begotten Son, Jesus Christ, whose blood was shed. Based on this, quite a number of scholars and translators acknowledge that the word “son” is to be understood here and render the phrase “with the blood of his own Son.”
