King James Version (KJV)
When thou didst terrible things {which} we looked not for, thou camest down, the mountains flowed down at thy presence.
Modern English
When you did awesome things which we didn’t look for, you came down, and the mountains quaked at your presence.
Hebrew
וּמֵעוֹלָ֥ם לֹא־שָׁמְע֖וּ לֹ֣א הֶאֱזִ֑ינוּ עַ֣יִן לֹֽא־רָאָ֗תָה אֱלֹהִים֙ זוּלָ֣תְךָ֔ יַעֲשֶׂ֖ה לִמְחַכֵּה־לֽוֹ׃
