'Period' in the Bible

And the period of dwelling of the {Israelites} that they dwelled in Egypt [was] four hundred and thirty years.

And he said to them, "This is what Yahweh has said. Tomorrow [is] a rest period, a holy Sabbath for Yahweh. Bake what you [want to] bake, and boil what you [want to] boil. Put aside all the surplus for yourselves for safekeeping until the morning."
