Psalms 70:5

But I [am] poor and needy
In ( Psalms 40:17 ) it follows, yet "the Lord thinketh on me"; instead of which it is here, (See Gill on Psalms 40:17);

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".
