(7) Fixed.--Better, steadfast (See Psalm 51:10, Note.)

Verse 7. - My heart is fixed, O God, my heart is fixed; or, my heart is steadfast - it does not doubt or waver, it is firm in its trust on thee. I will sing and give praise. Sing to thee, i.e., and praise thy Name.

57:7-11 By lively faith, David's prayers and complaints are at once turned into praises. His heart is fixed; it is prepared for every event, being stayed upon God. If by the grace of God we are brought into this even, composed frame of mind, we have great reason to be thankful. Nothing is done to purpose, in religion, unless it is done with the heart. The heart must be fixed for the duty, put in frame for it; fixed in the duty by close attention. Our tongue is our glory, and never more so than when praising God; dull and sleepy devotions will never be acceptable to God. Let us awake early in the morning, to begin the day with God; early in the beginning of a mercy. When God comes toward us with his favours, let us go forth to meet him with our praises. David desired to bring others to join in praising God; and in his psalms, he is still praising God among the people, singing to Him among the nations. Let us seek to have our hearts fixed to praise his boundless mercy and unfailing faithfulness; and to glorify him with body, soul, and spirit, which are his. Let us earnestly pray that the blessings of the gospel may be sent through every land.My heart is fixed, O God,.... Firm and sure, trusting in the Lord, believing that he should be saved by him out of his troubles; see Psalm 101:1. So, in a spiritual sense, a heart fixed and established, or that is firm and sure, is one that is assured of its salvation by Christ, rooted and grounded in the love of God, firmly built on the foundation, Christ, and has its affections set on him; and is unmoved, from the hope of the Gospel, and the doctrines of it, by whatsoever it meets with in the world. It may be rendered, "my heart is prepared", or "ready" (r); that is, according to some, to receive good or evil, prosperity or adversity, at the hand of God; to which sense is Jarchi's note,

"my heart is faithful with thee in the measure of judgment, and it is faithful with thee in the measure of mercy.''

That is, whether I am chastised with judgments, or followed with mercies, my heart is firm and true to God. The Targum is,

"my heart is prepared for thy law, O Lord; my heart is prepared for thy fear;''

that is, it is prepared for the worship and service of God; it is ready to every good work; it is prepared to pray unto him, and to wait for an answer, which are both from the Lord, Proverbs 16:1; and particularly to sing praise unto him, as follows;

my heart is fixed; this is repeated, to show the vehemency of his spirit, and the certainty of the thing;

I will sing and give praise; for the salvation wrought for him, and which he was sure of; and before he had finished this psalm, or while he had composed it, did enjoy it.
