כְּמ֤וֹ הָרָה֙ תַּקְרִ֣יב לָלֶ֔דֶת תָּחִ֥יל תִּזְעַ֖ק בַּחֲבָלֶ֑יהָ כֵּ֛ן הָיִ֥ינוּ מִפָּנֶ֖יךָ יְהוָֽה׃
Como la preñada cuando se acerca el parto gime, y da gritos con sus dolores, así hemos sido delante de ti, oh SEÑOR.
Ibn Ezra
Who established you expresses the same idea as Who bore you. Both refer to a God who is mighty and firm, like a rock. The word Who is established you probably derives from the triliteral root ḥ-y-l. Compare, “a pregnant woman, about to give birth” [Isaiah 26: 17].
