Exodus 30:20
Rahlfs Septuagint (1935) · Berean Standard Bible
ὅταν εἰσπορεύωνται εἰς τὴν σκηνὴν τοῦ μαρτυρίου νίψονται ὕδατι καὶ οὐ μὴ ἀποθάνωσιν ἢ ὅταν προσπορεύωνται πρὸς τὸ θυσιαστήριον λειτουργεῖν καὶ ἀναφέρειν τὰ ὁλοκαυτώματα κυρίῳ
Whenever they enter the Tent of Meeting or approach the altar to minister by presenting a food offering to the LORD, they must wash with water so that they will not die.
