pass through
Molech signifies a king, or governor, of similar import with Baâl, lord, or governor; and it is generally supposed that the sun was worshipped under this name; and more particularly as the fire appears to have been so much employed in his worship. It seems clear that children were not only consecrated to him by passing through the fire, which appears to be alluded to here, but that they were actually made a burnt offering to him. (See the parallel passages.) That the several abominations afterwards mentioned were actually practised by many heathen nations is abundantly attested by their own writers.
