Let my soul be filled as with marrow and fatness: and my mouth shall praise thee with joyful lips.

“"If I have remembered You upon my bed, in the dawnings I did meditate on you [Psalm 63:6]." His "bed" he calls his rest. When any one is at rest, let him be mindful of God; when any one is at rest, let him not by rest be dissolved, and forget God: if mindful he is of God when he is at rest, in his actions on God he does meditate. For the dawn he has called actions, because every man at dawn begins to do something. What therefore has he said? If therefore I was not mindful on my bed, in the dawn also I did not meditate on You. Can he that thinks not of God when he is at leisure, in his actions think of God? But he that is mindful of Him when he is at rest, on the Same does meditate when he is doing, lest in action he should come short.”

“When I remember thee upon my bed,.... Or "beds" (q); seeing he lay in many, as Kimchi observes, being obliged to flee from place to place. The sense is, that when he was on his bed in the night season, when alone, and free from worldly cares and fatigues, and called to mind the love of God to him, the past experience of his kindness, his promises to hits, and the fulfilment of them: that he should then be delightfully entertained, abundantly satisfied, slid his mouth be filled with songs of praise; and meditate on thee in the night watches; which the Jewish writers on the text say were three, as they were with the Jews, but with the Romans four; See Gill on Mat 14:25; and the night, in the times of Homer (r), was divided into three parts: the night season is a very proper one for meditation on the perfections, providences, promises, word and works of God; and which is very delightful and profitable, when attended with the presence, Spirit, and grace of God. The Targum is, "in the watches I will meditate on thy word.'' (q) "stratis meis", Pagninus, Montanus, Piscator, Cocceius; so Junius & Tremellius, Ainsworth. (r) Iliad. 10. v. 252, 253.”
