Psalms 80:18

So wilt not we go back from thee - We shall no more become idolaters: and it is allowed on all hands that the Jews were never guilty of idolatry after their return from the Babylonish captivity.

Quicken us - Make us alive, for we are nearly as good as dead.

We will call upon they name - We will invoke thee. Thou shalt be for ever the object of our adoration, and the center of all our hopes.

So will not we go back from thee - That is, if thou wilt thus interpose; if thou wilt deliver the nation; if thou wilt help him whom thou hast placed over it, giving him wisdom and valor, we will hereafter be obedient to thy law; we will not apostatize from thee. It is a solemn promise or pledge of future obedience made by the psalmist as expressing the purpose of the people if God would be merciful and would withdraw his judgments; a pledge proper in itself, and often made by the Hebrew people only to be disregarded; a pledge proper for all who are in affliction, and often made in such circumstances, but, as in the case of the Hebrews, often made only to be forgotten.

Quicken us - literally, Give us life. See the notes at Ephesians 2:1. Restore life to us as a people; save us from ruin, and reanimate us with thy presence.

And we will call upon thy name - We will worship thee; we will be faithful in serving thee.

80:18 Go back - Revolt from thee to idolatry or wickedness.Quicken - Revive and restore us to our tranquility.
