Exodus 12:14
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἔσται 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.
