O Zion, that bringest good tidings, get thee up into the high mountain; O Jerusalem, that bringest good tidings, lift up thy voice with strength; lift it up, be not afraid; say unto the cities of Judah, Behold your God! Behold, the Lord GOD will come with strong hand, and his arm shall rule for him: behold, his reward is with him, and his work before him. He shall feed his flock like a shepherd: he shall gather the lambs with his arm, and carry them in his bosom, and shall gently lead those that are with young.
Zion herself will be the herald of the good tidings of the Messiah’s advent. God showed the severity and His goodness — severity to those who refuse to acknowledge Him, but gentle goodness to His flock and lambs who have been dispersed among the Gentiles. These verses picture His coming in power and glory.
