2Ch 30:14
Before the slaying of the passover, in order to purify and sanctify the city for the feast, they removed the (illegal) altars and places for offering incense which had been erected under Ahaz (2Ch 28:24), and threw them into the Kidron (2Ch 29:16). מקטּרות is here a substantive: places for incense-offerings (cf. Ew. §160, e), and denotes altars intended for the offering of the קטרת.
