Псалтирь 138:8

Maschil--(See on Psa 32:1, title). When he was in the cave--either of Adullam (Sa1 22:1), or En-gedi (Sa1 24:3). This does not mean that the Psalm was composed in the cave, but that the precarious mode of life, of which his refuge in caves was a striking illustration, occasioned the complaint, which constitutes the first part of the Psalm and furnishes the reason for the prayer with which it concludes, and which, as the prominent characteristic, gives its name. (Psa 142:1-7) with my voice--audibly, because earnestly.

The Lord will perfect that which concerneth me,.... Or "will", or "may the Lord perform for me" (x): all things in providence; all that he had appointed for him, that would be for his good and his own glory, Psa 57:2; and particularly what concerned him as a king. He had made him king over the house of Judah; he had begun to fulfil his promise concerning the kingdom; and he would perfect it, by setting him over all the tribes of Israel. Also he believed he would perfect what concerned him as a saint, even the good work of grace upon his heart; which is but a begun work, is imperfect, is gradually carried on, and will be completed; God is able to do it, and none can hinder him; he has promised to do it, and he is faithful who will do it; and his glory is concerned in it; and it may be depended on it will be finished; he is a rock, and his work is perfect; see Phi 1:6; thy mercy, O Lord, endureth for ever; a phrase often used by the psalmist, with which his heart was affected; and here used, both as an argument by which he concluded God would perfect his begun work, and as an encouragement to make the following request: forsake not the works of thine own hands; as are all the works of providence and grace: the work of grace upon the heart may be expressed in the plural number, because of the several branches of it; which are all so many works, as the work of faith, labour, of love, &c. Th1 1:3; and which is the Lord's handiwork; and a curious work it is, a new creation work, a work of almighty power; and which he will never cease from, or be remiss in, as the word (y) signifies, until he has accomplished it, Th2 1:11. It is a prayer of faith, and may be most confidently believed: and some indeed render it as an expression of faith, "thou wilt not forsake the works of thin…

It does not appear, nor is it material to enquire, upon what occasion David penned this psalm; but in it, I. He looks back with thankfulness upon the experiences he had had of God's goodness to him (Psa 138:1-3). II. He looks forward with comfort, in hopes, 1. That others would go on to praise God like him (Psa 138:4, Psa 138:5). 2. That God would go on to do good to him (Psa 138:6-8). In singing this psalm we must in like manner devote ourselves to God's praise and glory and repose ourselves in his power and goodness. A psalm of David.

138:8 The psalmist expresses confidence in the Lord’s plans, which are perfect, and prays for God’s continued involvement. The psalmist sees himself as part of God’s plans (see 9:10; 139:14).
