Matthew Poole and continuators on Exodus 26:27

27 And five bars for the boards of the other side of the tabernacle; and five bars for the boards of the side of the tabernacle for the two sides westward .

There was but one side westward. Either therefore here is a transposition of the Hebrew words, which is usual, and the words are thus to be placed and rendred, westward looking to both sides, or, west-ward, according to both the other sides, now mentioned, to note that the number and length of bars in the west end should be equal to those on either of the other sides: or here is an Enallage of the number, the dual or plural for the singular, of which there are many examples, and so the words are to be rendred, for the side looking westward.
