Genesis 30:42

ובהעטיף WHEN THE FLOCKS WERE FEEBLE — the word has the meaning of “being late”, as the Targum renders it בלקישות the late-bearing ones (cf. מלקוש the “latter” rain). Menachem classifies it under the same root as (Isaiah 3:22) “the aprons and the mantelets (המעטפות)”, so that it has the meaning of wrapping oneself in a garment, and the word denotes those animals that are well wrapped up in their skin and fur so that they do not desire to be warmed by the males.

וּבְהַעֲטִ֥יף הַצֹּ֖אן לֹ֣א יָשִׂ֑ים וְהָיָ֤ה הָעֲטֻפִים֙ לְלָבָ֔ן וְהַקְּשֻׁרִ֖ים לְיַעֲקֹֽב׃

But when the cattle were feeble, he did not put them in: so the feebler were Lavan’s, and the stronger Ya῾aqov’s.
