Lord, all my desire is before thee - That is, Thou knowest all that I would ask or that I need. This is the expression of one who felt that his only hope was in God, and that He fully understood the case. There was no need of repeating the request. He was willing to leave the whole case with God.
And my groaning is not hid from thee - My sighing; the expression of my sorrow and anguish. As God certainly heard these sighs, and as He wholly understood the case, David hoped that He would mercifully interpose in his behalf.
