Therefore turn thou to thy God: keep mercy and judgment, and wait on thy God continually.
Therefore turn thou - who dost wish to be a true descendant of Jacob.
To thy God - who is therefore bound by covenant to hear thy prayers: literally, Do thou turn, or 'Thou shalt turn (so as to lean) ON thy God' [bª-].
Keep mercy and judgment - (Micah 6:8). These two include all the SECOND table commandments-duty toward one's neighbour, the most visible test of the sincerity of one's repentance.
And wait on thy God continually - on God alone, not on thy idols. Including all the duties of the FIRST table (Psalms 37:3; Psalms 37:5; Psalms 37:7; Psalms 40:1).
