Parallel
2 Chronicles 35:17
Swete's Septuagint · Berean Standard Bible
καὶ ἐποίησαν οἱ υἱοὶ Ἰσραὴλ οἱ εὑρεθέντες τὸ φάσεχ τῷ καιρῷ ἐκείνῳ καὶ τὴν ἑορτὴν τῶν ἀζύμων ἑπτὰ ἡμέρας.
The Israelites who were present also observed the Passover at that time, as well as the Feast of Unleavened Bread (note: That is, the seven-day period after the Passover during which no leaven may be eaten; see Exodus 12:14–20.) for seven days.
