Out of the mouth of babies and infants you have established praise

Possible meanings are 1) praise is spoken of as a solid object that God takes out of babies' mouths and sets up as a defensive wall or 2) God has created the world so that true praise comes to him from babies. Alternate translation: "You have given babies and infants the ability to praise you" or "It is babies and infants who truly praise you" (See: rc://en/ta/man/translate/figs-metaphor)
