(6) I will freely sacrifice.--Better, I will offer a willing (or freewill) sacrifice.

For it is good.--Comp. Psalm 52:9.

Verse 6. - I will freely sacrifice unto thee. Confidence has now mounted up to certainty. Regarding the deliverance as accomplished, the psalmist promises a freewill offering (Hengstenberg, Kay, Canon Cook) to God, so soon as he can approach the sanctuary. The phrase used is the ordinary one for sacrifices of thanksgiving (Numbers 15:3). I will praise thy Name, O Lord; for it is good (comp. Psalm 52:9).

54:4-7 Behold, God is mine Helper. If we are for him, he is for us; and if he is for us, we need not fear. Every creature is that to us, and no more, which God makes it to be. The Lord will in due time save his people, and in the mean time he sustains them, and bears them up, so that the spirit he has made shall not fail. There is truth in God's threatenings, as well as in his promises; sinners that repent not, will find it so to their cost. David's present deliverance was an earnest of further deliverance. He speaks of the completion of his deliverance as a thing done, though he had as yet many troubles before him; because, having God's promise for it, he was as sure of it as if it was done already. The Lord would deliver him out of all his troubles. May he help us to bear our cross without repining, and at length bring us to share his victories and glory. Christians never should suffer the voice of praise and thanksgiving to cease in the church of the redeemed.I will freely sacrifice unto thee,.... Not legal sacrifices; no, nor freewill offerings the law gives directions about, though the allusion is to them; but the freewill offerings of his mouth, Psalm 119:108; the sacrifices of praise and thanksgiving, on account of help, salvation, and deliverance, as appears from the following clause; which he determines to offer, not by constraint, but willingly; not by force, but of a ready mind; freely, and with all his heart. The sacrifice of his antitype is himself, his soul and body, as in union with his divine Person; and this was offered up to God, against whom man has sinned, and whose justice must be satisfied; and this was done freely and voluntarily; he gave himself an offering; he laid down his life of himself, and that for sinners. The sacrifices of his people are their prayers and praises, their acts of beneficence, and the presentation of their souls and bodies in divine service; all which they do freely, under the influence of divine grace;

I will praise thy name, O Lord; which explains what is meant by sacrificing: this is what is due to the Lord, and comely in his people;

for it is good; either the name of God; and therefore to be praised. He himself is good, as, he is, both in a way of providence and of grace; and it is good, both pleasantly and profitably good, to sing praises to him, Psalm 147:1.
