If Zechariah 9:9 refers to the First Advent of Christ, how does v. 10 relate to that?

“Behold, your King is coming to you;…riding on a donkey” (v. 9). Unlike Alexander the Great, this King comes riding on a donkey (Jer. 17:25). This was fulfilled at Christ’s Triumphal Entry into Jerusalem (Matt. 21:1–5; John 12:12–16). The Jews should have been looking for someone from the line of David (2 Sam. 7; 1 Chr. 17). Four elements in this verse describe the Messiah’s character: 1) He is King; 2) He is just; 3) He brings salvation; and 4) He is humble.

Zechariah moves to the Second Advent of Christ and the establishment of His universal kingdom in v. 10. “His dominion shall be ‘from sea to sea.’” Not characterized by bloodshed, the Messiah’s rule will be a kingdom of peace in which weapons of warfare will be destroyed or converted to peaceful uses (Is. 2:4; 9:5–7; 11:1–10; Mic. 5:2, 10–15), and peace spreads from the Euphrates River (the terminus of civilization) to the world.

The two advents of Christ are here compressed as though they were one as in Isaiah 61:1–3 (Luke 4:16, 21). Verse 9 refers to His First Coming and v. 10 is His Second. Old Testament prophets didn’t see the great time period between the two comings. The church age was a “mystery” hidden from them (Eph. 3:1–9; Col. 1:2
