Psalm 88:13

But unto thee have I cried, O LORD; and in the morning shall my prayer prevent thee.

But unto thee have I cried, O Lord,.... Formerly, and had been heard, answered, and relieved, and which was an encouragement to cry again to him in his distress; Christ was always heard, John 11:42, or, now, in his present case, yet was not heard, at least not immediately answered; which was the case of the Messiah, when forsaken by his God and Father, Psalms 22:1, yet still determines to continue praying, as follows:

and in the morning shall my prayer prevent thee; not before the Lord is awake, and can hear; for he neither slumbers nor sleeps, and he always hears: but the meaning is, that he would pray before he entered upon another business; this should be the first thing in the morning he would do, and this he would do before others did, or he himself used to do; before the usual time of morning prayer; signifying, he would pray to him very early, which is expressive of his vehemency, fervency, and importunity and earnestness, and what a sense he had of his case, and of his need of divine help: so Christ rose early in the morning, a great while before day, to pray, Mark 1:35.
