'Week' in the Bible

Finish the week [of the wedding feast] for Leah; then we will give you Rachel also, and in return you shall work for me for seven more years.”

So Jacob complied and fulfilled Leah’s week [of celebration]; then Laban gave him his daughter Rachel as his [second] wife.

You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread.’”

And he will enter into a binding and irrevocable covenant with the many for one week (seven years), but in the middle of the week he will stop the sacrifice and grain offering [for the remaining three and one-half years]; and on the wing of abominations will come one who makes desolate, even until the complete destruction, one that is decreed, is poured out on the one who causes the horror.”
