Lord, open my lips, and my mouth will express your praise

When David asks Yahweh to allow him to speak again, he refers to the part of his body he speaks with. Here not being able to speak is a symbol of being guilty of sin and not being able to make a defense. In this way, being allowed to speak means being forgiven of sin. AT: “Lord, allow me to speak, and I will be able to praise you.” (See: rc://en/ta/man/translate/figs-metonymy)
