Albert Barnes Commentary Psalms 27:6

"And now shall my head be lifted up above mine enemies round about me. And I will offer in his tabernacle sacrifices of joy; I will sing, yea, I will sing praises unto Jehovah." — Psalms 27:6 (ASV)

And now shall my head - Now I shall be exalted. So we say that in affliction a person bows down his head; in prosperity he lifts it up. This verse expresses the confident expectation that he would be enabled to triumph over all his foes, and a firm purpose on his part, as the result of this, to offer sacrifices of praise to his great Deliverer.

Above my enemies around me - All my enemies, though they seem even to encompass me on every side.

Therefore I will offer in his tabernacle - In His tent, His dwelling-place: referring here, undoubtedly, to “the tabernacle” as a place where God was worshipped.

Sacrifices of joy - Margin, as in the Hebrew, of “shouting.” That is, he would offer sacrifices accompanied with loud sounds of praise and thanksgiving. There is nothing wrong in shouting for joy when a person is delivered from imminent danger, nothing wrong in doing so when he feels that he is rescued from the peril of eternal ruin.

I will sing, indeed, I will sing praises to the Lord - This language is that which comes from a full heart. He is not content with saying merely that he would “sing.” He repeats the idea; he dwells upon it. With a heart overflowing with gratitude he would go and give utterance to his joy. He would repeat, and dwell upon, the language of thanksgiving.
