Isaiah 12:4-6

LXX2012(i) 4 And in that day you shall say, sing to the Lord, call aloud upon his name, proclaim his glorious [deeds] among the Gentiles; make mention that his name is exalted. 5 Sing praise to the name of the Lord; for he has done great [things]: declare this in all the earth. 6 Exalt and rejoice, you⌃ that dwell in Sion: for the Holy One of Israel is exalted in the midst of her.
