וְהָיָ֗ה בְּכָל־יַחֵם֮ הַצֹּ֣אן הַמְקֻשָּׁרוֹת֒ וְשָׂ֨ם יַעֲקֹ֧ב אֶת־הַמַּקְל֛וֹת לְעֵינֵ֥י הַצֹּ֖אן בָּרֳהָטִ֑ים לְיַחְמֵ֖נָּה בַּמַּקְלֽוֹת׃
Y sucedía que cuantas veces se recalentaban las tempranas, Jacob ponía las varas delante de las ovejas en las pilas, para que concibiesen á la vista de las varas.
Ibn Ezra
הנחמים באלים The best of the various explanations of this phrase is that it refers to idolatry;4The noun אלים signifies here trees under which idols were worshipped. See Rashi and Targum ad locum. הנחמים Who are conceived, similar in form to הנצבים that stood (Gen. 45:1), is the Niphal of יחם to conceive; comp. בכלּ יַחֵם whensoever (the stronger cattle) did conceive (Gen. 30:41). This expression is the description of children of transgression (ver. 4); comp., And in sin did my mother conceive me (Ps. 51:7).
