Exodus 29:35
Swete's Septuagint · Berean Standard Bible
καὶ ποιήσεις Ἀαρὼν καὶ τοῖς υἱοῖς αὐτοῦ οὕτως κατὰ πάντα ὅσα ἐνετειλάμην σοι · ἑπτὰ ἡμέρας τελειώσεις αὐτῶν τὰς χεῖρας.
This is what you are to do for Aaron and his sons based on all that I have commanded you, taking seven days to ordain them.
