Albert Barnes Commentary Ezekiel 40:43

"And the hooks, a handbreadth long, were fastened within round about: and upon the tables was the flesh of the oblation." — Ezekiel 40:43 (ASV)

Hooks - The alternative renderings given in the margin indicate the uncertainty of the translation of the original word. The form is dual and indicates that it is some object usually found in pairs.

Some suggest that they were borders or ledges set on either side of the tables, a handbreadth from the edges, to prevent the instruments placed on them from falling off.

If the rendering “hooks” is adopted, it is to be explained as follows: that these hooks were set on the wall “within,” that each hook was forked (hence, the “dual” form) and projected from the wall one span; and that on these hooks the carcasses of the slain animals were hung.
