"Praise you the LORD. Praise, O you servants of the LORD, praise the name of the LORD.” (v.1)
Jon Courson tells us in his commentary that Psalm 113 is the first of six consecutive psalms called “halal psalms” or praise psalms because most of them start or end with the Hebrew word, halal, or “praise.” And that these songs were sung at the three major feasts or festivals of the Jews: Passover, Pentecost, and Tabernacles. Praise was the essential offering at all the solemn feasts of the people of God. Prayer was the myrrh, and praise the frankincense, and both of these must be presented unto the Lord, just as they were at our Savior’s birth.
What I find interesting about this psalm is, who it is addressed to. Not the angels, nor all men, nor the priests and Levites only (but it certainly included them); but all the servants, saints, God’s faithful people, who are a holy priesthood, to offer up spiritual sacrifices (praise) to God. And even though these songs were traditionally sung at the major feasts, I believe this to be a call to worship Him daily since, "His mercies are new every morning."
Therefore, “praise ye the Lord” you His servants, praise the name of Jehovah.
The Truth: "Praise the LORD! Sing to the LORD a new song, And His praise in the congregation of the godly ones.” (Psalm 149:1) -NAS
