Numbers 22:24

במשעול — Understand this as the Targum does: IN A PATH. And similar is, (1 Kings 20:10) “If the dust of Samaria shall suffice לשעלים” — the dust that attaches itself to the soles of peoples’ feet when they walk. And similarly, (Isaiah 40:12) “Who hath measured the water בשעלו” — with his feet and through his walking (as one measures by pacing). גדר מזה וגדר מזה A FENCE BEING ON THIS SIDE AND A FENCE ON THAT SIDE — The term גדר without further definition is one of stone (and that is why in the next verse it is called a קיר which is a term for a stone wall; cf. Leviticus 14:37—40).

וַֽיַּעֲמֹד֙ מַלְאַ֣ךְ יְהֹוָ֔ה בְּמִשְׁע֖וֹל הַכְּרָמִ֑ים גָּדֵ֥ר מִזֶּ֖ה וְגָדֵ֥ר מִזֶּֽה׃

But the angel of the Lord stood in a path of the vineyards, a wall being on this side, and a wall on that side.
