The Lord hath heard my supplication - Repeating the sentiment in the previous verse, to express his assurance and his joy. Nothing is more natural in such circumstances than to dwell on the joyous thought, and to repeat it to ourselves, that it may make its full impression.
The Lord will receive my prayer - As he has done it, so he will still do it. This allays all fears of the future, and makes the mind calm. The state of mind here is this: “The Lord has heard my prayer; I am assured that he will do it hereafter; I have, therefore, nothing to fear.”
