(20) Who hath not turned . . .--i.e., he found himself able to pray, was not silenced. Notice the zeugma. God had not rejected his prayer nor withdrawn His grace.

Verse 20. - Blessed be God, which hath not turned away my prayer, nor his mercy from me. The psalm of thanksgiving appropriately concludes with a special blessing of God by the psalmist, who felt that such especial mercy had been shown to himself (vers. 16-20).

66:13-20 We should declare unto those that fear God, what he has done for our souls, and how he has heard and answered our prayers, inviting them to join us in prayer and praise; this will turn to our mutual comfort, and to the glory of God. We cannot share these spiritual privileges, if we retain the love of sin in our hearts, though we refrain from the gross practice, Sin, regarded in the heart, will spoil the comfort and success of prayer; for the sacrifice of the wicked is an abomination of the Lord. But if the feeling of sin in the heart causes desires to be rid of it; if it be the presence of one urging a demand we know we must not, cannot comply with, this is an argument of sincerity. And when we pray in simplicity and godly sincerity, our prayers will be answered. This will excite gratitude to Him who hath not turned away our prayer nor his mercy from us. It was not prayer that fetched the deliverance, but his mercy that sent it. That is the foundation of our hopes, the fountain of our comforts; and ought to be the matter of our praises.Blessed be God, which hath not turned away my prayer,.... Has not been angry against it, shut it out, or covered himself with a cloud that it might not pass through, which sometimes saints have complained of, Psalm 80:4; but graciously heard and received it;

nor his mercy from me; for that endures for ever, and is from everlasting to everlasting on them that fear the Lord, Psalm 103:17; all which require thankfulness and praise, which is here given.
