'Halfway' in the Bible

And the middle bar in the center of the boards shall pass through [horizontally] from end to end.

And you shall put it under the ledge of the altar, so that the grid will extend halfway up the altar.

And he made the middle bar pass through [horizontally] halfway up the boards from one end to the other.

He made for the altar a grating of bronze mesh under its rim, extending halfway up it.
