כִּֽי־חֵ֭מָה פֶּן־יְסִֽיתְךָ֣ בְסָ֑פֶק וְרָב־כֹּ֝֗פֶר אַל־יַטֶּֽךָּ׃
너는 분격함을 인하여 징책을 대적하지 말라 대속함을 얻을 일이 큰즉 스스로 그릇되게 말지니라
Rashi
and with children of gentiles they please themselves They cohabit with the daughters of the heathens and mingle with them, and they would bear children to them, with whom they are always pleased, and they occupy themselves [with them] and long for them and bother with them. This is an expression similar to [that of] (Job 36:18) “lest he incite you because of abundance (בְּשֶׂפֶק)” [debatement in O.F].
