The children of thy servants shall continue, and their seed shall be established before thee.
The children of thy servants shall continue - literally, 'shall dwell' or 'inhabit' their own land, the land of Yahweh. Psalms 37:27; Psalms 37:29; Psalms 69:35-36, are strikingly parallel. Dwell is the opposite of wandering about without home (Psalms 68:6). Thy servants are the Israelite nation (called "Jacob" and "Judah" in Isaiah 65:9), which from its forefathers, Abraham, Isaac, and Jacob, with whom God made the covenant, was the servant of God.
And their seed. The children and the seed are the genuine children for Israel, the seed that shall be spiritually born (Psalms 22:30-31; Isaiah 66:8-9).
Shall be established before thee - (Genesis 17:1; Psalms 89:37: especially Psalms 101:7, margin.) Liars shall not be established before the coming Son of David; the seed of His servants shall be established before Him (cf. Zephaniah 3:13).
