2 Samuel 6:12-14
12. it was told king David, saying, The Lord hath blessed the house of Obed-edom, and all that pertaineth unto him, because of the ark of God—The lapse of three months not only restored the agitated mind of the monarch to a tranquil and settled tone, but led him to a discovery of his former error. Having learned that the ark was kept in its temporary resting-place not only without inconvenience or danger, but with great advantage, he resolved forthwith to remove it to the capital, with the observance of all due form and solemnity (1Ch 15:1-13). It was transported now on the shoulders of the priests, who had been carefully prepared for the work, and the procession was distinguished by extraordinary solemnities and demonstrations of joy.
13. when they that bare the ark . . . had gone six paces—Some think that four altars were hastily raised for the offering of sacrifices at the distance of every six paces (but see on 1Ch 15:26).
14. David danced before the Lord—The Hebrews, like other ancient people, had their sacred dances, which were performed on their solemn anniversaries and other great occasions of commemorating some special token of the divine goodness and favor.
with all his might—intimating violent efforts of leaping, and divested of his royal mantle (in a state of undress), conduct apparently unsuitable to the gravity of age or the dignity of a king. But it was unquestionably done as an act of religious homage, his attitudes and dress being symbolic, as they have always been in Oriental countries, of penitence, joy, thankfulness, and devotion. [See on 1Ch 15:27.]Psalms 30:11
11. sackcloth—was used, even by kings, in distress (1Ch 21:16; Isa 37:1) but "gladness," used for a garment, shows the language to be figurative.
