2 Chronicles 35:17
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And the children of Israel that were present (note: Heb. found) kept the passover at that time, and the feast of unleavened bread seven days.
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.
