פירוש על שמואל ב 12:30

The crown of Malkom. The abomination [idol] of the people of Ammon's name was Malkom. Denoting [the word] Moleich.¹⁰מוֹלֶךְ is an idol to whom children were sacrificed.

It was [hung over] Dovid's head. Itai the Gitite annulled it.¹¹This explanation of the verse is stated in Avodah Zoroh 24. It is prohibited for Jews to derive any pleasure from the idols of gentiles. They must be anulled by a gentile, i.e., taken out of the service of idol worship, after which they are permitted to Jews. Itai the Gitite, a gentile, did this to Malkom for Dovid’s sake.
