But I [am] poor and needy,.... In Psalms 40:17 it follows, yet "the Lord thinketh on me"; instead of which it is here,
make haste unto me, O God; which repeats for sense the same petition as in Psalms 71:1;
thou [art] my help and my deliverer; O Lord, make no tarrying; in
Psalms 40:17 it is, "O my God".
