כִּֽי־חֵ֭מָה פֶּן־יְסִֽיתְךָ֣ בְסָ֑פֶק וְרָב־כֹּ֝֗פֶר אַל־יַטֶּֽךָּ׃
Sebab murka itu besar; jangan sampai engkau terbujuk oleh kelimpahanmu, sebab tebusan yang besar pun tidak akan dapat menghindarkanmu dari murka itu.
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].
