Éxodo 38

And he drew them through the rings, which projected from the sides of the altar. But the altar itself was not solid, but hollow, made from panels and empty inside.

Y metió las varas por los anillos á los lados del altar, para llevarlo con ellas: hueco lo hizo, de tablas.

And he put the staves into the rings on the sides of the altar, to bear it withal; he made the altar hollow with boards.

He put the poles into the rings on the sides of the altar, with which to carry it. He made it hollow with planks.
