Exodus 12:14
Swete's Septuagint · Berean Standard Bible
καὶ ἱστᾶι ἡ ἡμέρα ὑμῖν αὕτη μνημόσυνον, καὶ ἑορτάσετε αὐτὴν ἑορτὴν κυρίῳ εἰς πάσας τὰς γενεὰς ὑμῶν· νόμιμον αἰώνιον ἑορτάσετε αὐτήν.
And this day will be a memorial for you, and you are to celebrate it as a feast to the LORD, as a permanent statute for the generations to come.
