So will not we go back from thee: quicken us, and we will call upon thy name.
So will not we go back from thee. No longer can Israel say as in Psalms 44:18. But they promise not to "go back" from the Lord anymore, if only the Lord will first quicken them; i:e., give them new life.
Quicken us, and we will call upon thy name (Psalms 71:20). God must first breaths into us the spirit of adoption, before we can call on Him as our Father (Romans 8:15).
