The right sacrifices (Ps 4:4-4:5)

“When you are disturbed

Do not sin!

Mediate about it on your beds!

Be silent!

Selah

Offer right sacrifices!

Put your trust in Yahweh!”

However, there was a caveat to this self-righteousness. You could not sin even if you were a little disturbed. You had to meditate while you were in bed. You had to be silent in your prayer. After this mention of silence, there is a pause for a musical interlude. You had to offer the right sacrifices. Apparently this psalm might have been used when burnt offerings or evening sacrifices were being made. You had to put your trust in Yahweh, and not in yourself.
