VAU. Let thy mercies come also unto me, O Lord
Meaning not his providential mercies, but his special mercies and favours; his mercies of old, which were upon his heart and thoughts from everlasting; the sure mercies of David, or the blessings of the everlasting covenant; the spiritual blessings, wherewith the saints are blessed in Christ; the grace that was given to them in him, before the world was: these are desired by the psalmist to be remembered, shown, communicated, and applied unto him, and, as it were, that they might come into his heart and soul; which is done when the love of God is shed abroad there, when full flows of it come in, and all grace is made to abound, and every want is supplied;
[even] thy salvation, according to thy word;
not temporal, but spiritual and eternal salvation; which God has appointed his people to, secured for them in covenant, promised them in Christ, whom he sent to work it out, and which is in him; and which in the effectual calling comes to the soul, being brought near and applied to a sensible sinner by the Spirit of God. Here a fresh view of interest in it, a fresh visit with it, and a restoration of the joys of it, are desired; and which salvation flows from the abundant mercy and free favour of God in Christ; and is, according to his word of promise, spoken by the mouth of all his holy prophets, from the beginning of the world; and may here respect the particular word of promise made to David, that God would put away his sin, and save him, and that he should not die, ( 2 Samuel 12:13 ) ; or his word of promise in general, to all that seek and call upon the Lord, that they shall find grace and mercy, and be saved everlastingly.
