I came to the exiles at Tel Abib, ¹  who lived by the Kebar River. ²  I sat dumbfounded among them there, where they were living, for seven days. ³

In the seventh month, on the fifteenth day of the month, at the feast, ¹  he will make the same provisions for the sin offering, burnt offering, and grain offering, and for the olive oil, for the seven days.
