Psalms 111:1

I will praise the Lord with my whole heart - If we profess to "sing to the praise and glory of God," the heart, and the whole heart, without division and distraction, must be employed in the work.

In the assembly - בסוד besod, in the secret assembly - the private religious meetings for the communion of saints. And in the congregation, עדה edah, the general assembly - the public congregation. There were such meetings as the former ever since God had a Church on the earth; and to convey general information, there must be public assemblies.

Praise ye the Lord - Margin, "Hallelujah." See Psalm 106:1.

I will praise the Lord with my whole heart - With undivided affections; holding back nothing. I will allow nothing to be in my heart that would interfere with the fullness of praise; no coldness or dividedness of affection; no love for other things that would deaden my love for God; no suspicion respecting him that would chill my ardor; no unbelief that would drag me down to earth, while the language of my lips ascended to God. See the notes at Psalm 86:12.

In the assembly of the upright - With the righteous when they are gathered together for public worship.

And in the congregation - See Psalm 22:22, Psalm 22:25; Psalm 66:13; Psalm 89:5.
