My praise shall be of thee - That is, I will praise thee. I will call to remembrance thy goodness, and will unite with others in celebrating thy faithfulness and lovingkindness.
In the great congregation - See the notes at Psalms 22:27.
I will pay my vows before them that fear him - In the presence of his worshippers. That is, he would keep the vows which in his afflictions he had made, that he would praise and serve God. These vows or promises were of the nature of a “debt” which he says he would remember to pay. Of the Redeemer, this need not be understood personally, but it means that as the result of his prayer having been heard, the worship of God would be celebrated by those who feared him. The solemn worship of the people of God - the praises which they offer to the Most High - may be regarded as worship paid by the Redeemer himself, for he does it in the persons and services of those whom he redeemed. All the praises which proceed from their hearts and lips are the fruit of his “vows,” of his fidelity, and his prayers.
