'Lips' in the Bible

while you on your part lend us your aid in entreaty for us, so that from many lips thanksgivings may rise on our behalf for the boon granted to us at the intercession of many.

On Christ's behalf therefore we come as ambassadors, God, as it were, making entreaty through our lips: we, on Christ's behalf, beseech men to be reconciled to God.

O Corinthians, our lips are unsealed to you: our heart is expanded.

If however I should choose to boast, I should not be a fool for so doing, for I should be speaking the truth. But I forbear, lest any one should be led to estimate me more highly than what his own eyes attest, or more highly than what he hears from my lips.

since you want a practical proof of the fact that Christ speaks by my lips--He who is not feeble towards you, but powerful among you.
