American Standard Version (ASV):
And these are the measures of the altar by cubits (the cubit is a cubit and a handbreadth): the bottom shall be a cubit, and the breadth a cubit, and the border thereof by the edge thereof round about a span; and this shall be the base of the altar.
King James Version (KJV):
And these [are] the measures of the altar after the cubits: The cubit [is] a cubit and an hand breadth; even the bottom [shall be] a cubit, and the breadth a cubit, and the border thereof by the edge thereof round about [shall be] a span: and this [shall be] the higher place of the altar.
