וָאֵרֵ֖ד בֵּ֣ית הַיּוֹצֵ֑ר והנהו [וְהִנֵּה־] [ה֛וּא] עֹשֶׂ֥ה מְלָאכָ֖ה עַל־הָאָבְנָֽיִם׃
Lalu aku turun ke rumah tukang periuk, dan lihatlah, ia sedang mengerjakan pekerjaannya di atas roda pemutar.
Rashbam
על האבנים; on the birth-chair. We encounter this expression משבר meaning birth-chair in Kings II 19,3 באו בנים עד המשבר, “the babes have reached the birth-stool.” The expression אבנים also occurs in Jeremiah 18,3 where it describes a tool similar to round millstones.
Rashi
על האבנים UPON THE STOOLS — the seat for the woman in the act of childbirth; in another passage (Isaiah 37:3) Scripture terms it מַשְׁבֵּר. Similar is, (Jeremiah 18:3) “He was at work on the אבנים" — the place of the vessels of (being produced by) the craftsmanship of the potter.
