Charles Ellicott Commentary Jeremiah 10:10

"But Jehovah is the true God; he is the living God, and an everlasting King: at his wrath the earth trembleth, and the nations are not able to abide his indignation." — Jeremiah 10:10 (ASV)

The Lord is the true God. —Literally, Jehovah is the God that is Truth. The thought expressed is that for which St. John, as indeed the Septuagint does here, uses the word alēthinos (John 17:3; 1 John 5:20), Truth in its highest and most perfect form. So I am the way, the truth, and the life (John 14:6).

An everlasting king. —Here, as in other like passages, the English Version is not wrong, but the Hebrew idiom “King of Eternity” is far grander.
