'Surplus' in the Bible

When they measured it by quarts, the person who gathered a lot had no surplus, and the person who gathered a little had no shortage. Each gathered as much as he needed to eat.

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."

The overlapping part that is left over from the tent curtains, the half curtain that is left over, shall lap over the back of the tabernacle.

And a cubit {from one side} and a cubit {from the other side} in the surplus in the length of the curtains of the tent will be hung over the sides of the tabernacle {equally} to cover it.
