“make yourselves holy.” The people were to do what it took to make themselves holy in the sight of God (cp. Lev. 11:44). David understood the value of people who handled the things of God to make themselves holy in God’s sight. This is important for Christians to keep in mind too, because we handle the Word of God, the people of God, God’s money, etc. This is not to be done carelessly or in an ungodly way. [For more on “make yourselves holy,” see commentary on Joshua 3:5].
