Charles Ellicott Commentary Jeremiah 15:16

"Thy words were found, and I did eat them; and thy words were unto me a joy and the rejoicing of my heart: for I am called by thy name, O Jehovah, God of hosts." — Jeremiah 15:16 (ASV)

Thy words were found ... —The words go back to the mission of Jeremiah 1, and paint, with a wonderful power, the beginning of a prophet’s work, the new-born intensity of joy in the sense of communion with the Eternal. The soul feeds on the words that come to it (see the same figure in a bolder form in Ezekiel 2:8; Ezekiel 3:1–3; Revelation 10:9). They are sweeter than honey and the honeycomb (Psalms 19:10). They are incorporated with its life, are the rejoicing of its heart. He is called by the Name of the Lord God of hosts, or, more literally, that Name is called upon him. As the witness of his special consecration, he becomes, like other prophets, a man of God (1 Kings 13:1; 2 Kings 7:2; 1 Timothy 6:11).
