The preparations of the heart belong to man, but the answer of the tongue, is from the LORD.
All Commentaries on Proverbs 16:1 Go To Proverbs 16
Richard Challoner
AD 1781
It is the part of man: That is, a man should prepare in his heart and soul what he is to say: but after all, it must be the Lord that must govern his tongue, to speak to the purpose. Not that we can think any thing of good without God's grace; but that after we have (with God's grace) thought and prepared within our souls what we would speak, if God does not govern our tongue, we shall not succeed in what we speak.
