Psalm 149:5 New English Translation

⁵Let the godly rejoice because of their vindication.^[a]
Let them shout for joy upon their beds.^[b]

Psalm 149:5 tn Heb “in glory.” Here “glory” probably refers to the “honor” that belongs to the Lord’s people as a result of their deliverance (see v. 4).
Psalm 149:5 tn The significance of the reference to “beds” is unclear. Perhaps the point is that they should rejoice at all times, even when falling asleep or awaking.
