'Seven' in the Bible

And I went to the exiles [at] Tel Abib, who [were] dwelling near the {Kebar River}, and I sat [where] they [were] dwelling. I sat there seven days in the midst of them, stunned.

And then it happened at [the] end of seven days, {the word of Yahweh came} to me, saying,

"?"And the inhabitants of the towns of Israel will go out, and they will set ablaze, and they will kindle a fire with a weapon and a small shield and a shield, [with] a bow and with arrows, and with {hand clubs} and with spears, and [so] they will light a fire with them, {a fire lasting seven years}.

And the house of Israel will bury them for seven months to cleanse the land.

?"And they will set apart {men to continually} go through the land burying the travelers, the ones left over on [the] surface of the land to cleanse it; {for the whole of} seven months they will explore [it].

And its windows and its porticos and its palm tree images [were] like the measurement of the gate that [was] {facing toward the east}; and {it had} seven steps that go up it, and [there were] porticos {before them}.

And seven steps [were] going up [to] it and its porticos {before them}. And {it had palm tree images} {all along} its pilasters.

And he went into [the] inner [room], and he measured the pilaster of the doorway [as] two cubits and the doorway [as] six cubits and the width of the doorway seven cubits.

[For] seven days you must provide a goat of sin offering for the day and a bull, {a calf}, and a ram from the flock without defect; you must provide [them].

Seven days they must purify the altar and they must cleanse it and [so] {they will consecrate it}.

And, after his cleansing, they shall count for him seven days,

In the first [month], on the {fourteenth} day of the month, you shall have the Passover, feast [lasting for] {seven days}, [when] you shall eat unleavened breads.

And [during] the seven days of the religious feast he shall provide [as] a burnt offering to Yahweh seven bulls and seven rams without defect for each of the seven days, and [as] a sin offering a he-goat for each day.

In the seventh [month], on the {fifteenth} day of the month, during the feast, he shall provide just as [he has for] these seven days, as [he did for] the sin offering, [as he did for] the burnt offering, and [as he did] for the grain offering, and [as he did] for the olive oil.'"
