'Seven' in the Bible

I came to the exiles at Tel-abib by the Chebar River and sat down among them for seven days, appalled.

At the end of the seven days, this message from the LORD came to me:

"After all this happens, the people who live in the cities of Israel will be kindling fires for seven years, using small shields, large shields, bows, arrows, clubs, personal weapons, and spears to do so.

The house of Israel will be burying them for seven months in order to purify the land.

"Men will be assigned to travel continuously throughout the land, exploring for seven full months as they go about burying the bodies that remain from the battle on the surface of the ground, so that the land may be sterilized.

Its windows, porches, and palm tree ornaments had measurements identical to the east-facing gate. Reached by seven ascending steps, its porch lay to the front of the steps.

Seven steps led up to it, with a porch in front of them. Palm tree ornaments were engraved on its side pillars, one on each side.

Then he went inside and measured the door jambs at two cubits wide and the doorway at six cubits high. The doorway was seven cubits wide.

For a seven day period they are to make atonement for the altar, purifying it and consecrating it.

After he is cleansed from that contact, he is to not to minister for seven days.

""On the fourteenth day of the first month, you are to observe the Passover as a festival for seven days. Unleavened bread is to be eaten.

Each day during the seven days of the festival, he is to provide a burnt offering to the LORD, consisting of seven bulls and seven rams without defect, offered each day throughout the seven days, along with a male goat offered each day as a sin offering.

On the fifteenth day of the seventh month, during a seven day festival, the Regent Prince is to present these as daily sin offerings, burnt offerings, and grain offerings mixed with oil.'"
