I shall surely remember thee, etc. It may be read also, when, or, as often as I remember thee, I will pray in the night watches. But as the Hebrew particle here used is occasionally taken for an adverb of affirmation, as well as of time, I have adhered to the commonly received translation, In this case, his remembering God is to be understood as the same thing with his meditating upon him; and the one clause contains just a repetition of the sentiment expressed in the other. If the particle be taken in the different sense formerly mentioned, the words intimate, that as often as the name of God recurred to his mind, he would dwell upon it with pleasure, and speak of his goodness. He particularly mentions the night watches, as, when retired from the sight of our fellow-creatures, we not only revert to what may have given us anxiety, but feel our thoughts drawn out more freely to different subjects. We have next the reason assigned for the engagement or declaration he has just made, which is, that he owed to God his preservation. The experience of the divine goodness should dispose us to prayer as well as praise. "I will come into thy house," says the Psalmist in another place, "in the multitude of thy mercy," (Psalm 5:7.) The second part of the seventh verse is expressive of the lively hope with which he was animated. He was resolved to rejoice and triumph under the shadow of God's wings, as feeling the same peace and satisfaction in reliance upon his protection as he could have done had no danger existed.

When I remember thee upon my bed - See the notes at Psalm 42:8. That is, when I lie down at night; when I compose myself to sleep. Nothing can be more proper than that our last thoughts, as we sink into quiet slumber, should be of God; of his being, his character, his mercy, his loving-kindness; of the dealings of his providence, and the manifestations of his grace toward us, during the day; and nothing is better suited to compose the mind to rest, and to induce quiet and gentle slumber, than the calmness of soul which arises from the idea of an Infinite God, and from confidence in him. Often when restless on our beds - when nothing else will lull the body to rest, the thought of God - the contemplation of his greatness, his mercy, and his love - the sweet sense of an assurance of his favor will soothe us, and cause us to sink into gentle repose. So it may be - so it will be - when we are about to sleep the long sleep of death, for then the most appropriate thoughts - the thoughts that will best prepare us for that long sleep - will be thoughts of God.
And meditate on thee in the night-watches - See the notes at Psalm 1:2. The word watches here refers to the ancient divisions of the night for municipal or military purposes - periods of the night assigned to different persons to keep watch around a camp or city. The most common division of the night was into three parts, though the arrangement varied at different times. See Matthew 14:25; Luke 12:38.

When I remember thee upon my bed - I will lie down in thy fear and love; that I may sleep soundly under thy protection, and awake with a sense of thy presence and approbation; and when I awake in the night watches, or be awakened by them, I will spend the waking moments in meditation upon thee.

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 Matthew 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.''

night--as well as day. Past favors assure him of future, and hence he presses earnestly near to God, whose power sustains him (Psalm 17:8; Psalm 60:5).
