John Calvin on Joel 3:15

I have already explained this verse in chapter 2: the Prophet, as we then stated, describes in these words the terrible judgment of God, in order to shake off the indifference of men, who carelessly hear and despise all threatening, except the Lord storms their hearts. These figurative expressions then are intended to awaken the ungodly, and to make them know that it is a serious matter when the Lord proclaims his judgment. Let us now go on with the passage —

Joel 3:16

16. The LORD also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the LORD will be the hope of his people, and the strength of the children of Israel.

16. Et Jehova e Sion rugiet, et e Jerusalem dabit (edat) vocem suam; et contremiscent coeli et terra: et Jehova spes erit populo suo, et fortitudo filiis Israel.
