20 Blessed be God! who hath not turned away my prayer He concludes the psalm, as he began it, with thanksgiving, and gives the reason of his not having met with a repulse; or, to take the figurative expression which he employs, of God’s not having turned away his prayer. This was, that he had not withdrawn his mercy. For it is entirely of his free grace that he is propitious, and that our prayers are not wholly ineffectual.
