'Rim' in the Bible

And these [are] the measurements of the altar in the cubits (a cubit [is] a cubit and a handbreadth): now its gutter {is a cubit in depth by a cubit in width} and its rim along its edge all around is one span, and this [is] [also] the height of the altar.

And the ledge [was] {fourteen} [cubits] in length with {fourteen} [cubits] [its] width to [all] four of its sides, and a rim [was] all around it of one-half cubit. And the gutter for it [was] a cubit all around, and its steps [were] facing east."

You must take some of its blood and put [it] on {the four horns of the altar}, and the four corners of the ledge, and on the rim all around; thus you must purify it and make atonement for it.
