Zechariah 12:5

“And the governors of Judah shall say in their heart, etc.] The governors of the rest of the cities in Judea, besides Jerusalem, when they shall observe the armies of the people, their horses and their riders, smitten by the Lord, as above, shall take heart, and be of good courage: and secretly say within themselves, The inhabitants of Jerusalem [shall be] my strength in the Lord of hosts their God; that is, they, in the strength of the Lord, shall overcome their enemies, and so be the means of preserving and securing the other cities of Judah from destruction: the governors do not place their strength and confidence in the inhabitants of Jerusalem, but as they are strengthened in and by the…”

“shall say--when they see the foe divinely smitten with "madness." Judah . . . Jerusalem--here distinguished as the country and the metropolis. Judah recognizes her "strength" to be "Jerusalem and its inhabitants" as the instrument, and "Jehovah of hosts their God" (dwelling especially there) as the author of all power (Joe 3:16). My strength is the inhabitants of Jerusalem, who have the Lord their God as their help. The repulse of the foe by the metropolis shall assure the Jews of the country that the same divine aid shall save them.”

“And the princes of Judah - He pictures the onemindedness of the Church. No one shall assume anything to himself; each shall exalt the strength which the other was to him; but all, “in the Lord. The princes of Judah” shall say “in their heart,” not outwardly or politically, but in inward conviction, “strength to me” (all speak as one) “are the inhabitants of Jerusalem in the Lord of hosts their God.” The highest in human estimation acknowledge that their strength is in those who are of no account in this world; as, in fact the hearts of the poor are evermore the strength of the Church; but that, “in the Lord of hosts;” in Him, in whose hands are the powers of heaven and earth, over against…”

“The inhabitants of Jerusalem - Though but few, and poor, yet they shall be my strength. Not in their own power, but in the power of the Almighty Lord of all. Zechariah 12:6”

“12:5 the Lord of Heaven’s Armies: This title emphasizes God’s irrepressible power (see study note on 1:3). The frequent repetition of this title in Zechariah’s second oracle (chs 12–14) assured his audience that the divine promises concerning Judah’s victory would certainly be fulfilled (12:7).”

“the governors: Zac 12:6; Jdg 5:9; Isa 1:10, Isa 1:23, Isa 1:26, Isa 29:10, Isa 32:1, Isa 60:17; Jer 30:21, Jer 33:26; Eze 45:8, Eze 45:9 The inhabitants: etc. or, There is strength to me, and to the inhabitants, etc. Zac 10:6, Zac 10:12; Psa 18:32, Psa 18:39, Psa 20:6, Psa 20:7, Psa 46:1, Psa 68:34, Psa 68:35, Psa 118:10-14, Psa 144:1; Isa 28:6, Isa 41:10-16; Joe 3:16; Co2 12:9, Co2 12:10 Zechariah 12:6”

“Zac 12:5. "And the princes of Judah will say in their hearts, The inhabitants of Jerusalem are strength to me, in Jehovah of hosts their God. Zac 12:6. On that day will I make the princes of Judah as a basin of fire under logs of wood, and like a torch of fire under sheaves; and they will devour all nations round about, on the right and on the left; and Jerusalem will dwell still further in its place, at Jerusalem. Zac 12:7. And Jehovah will save the tents of Judah first, that the splendour of the house of David and the splendour of the inhabitants of Jerusalem may not lift itself up over Judah." The princes of Judah are mentioned as the leaders of the people in war. What they say is the…”
