Therefore they sacrifice unto their net, and burn incense unto their drag,.... Either to their idols, to fortune and the stars, as Aben Ezra; imagining they gave them success, and prospered them in the arts and methods they used: or to their arms, as the Targum; nor was it unusual with the Heathens to worship their spears, sacrifice to them, and swear by them .
So Justin says , originally the ancients worshipped spears for gods, in memory of whose religion spears are still added to the images of the gods. Lucian asserts that the Scythians sacrificed to a scimitar; and Arnobius says the same; and Ammianus Marcellinus reports, that the Quadi worship their swords or daggers instead of gods; and that it was usual to swear by the spear is evident from others .
Or else the sense is, they sacrificed to their own valour and courage, skill and conduct.Because by them their portion [is] fat, and their meat plenteous: that is, by their angle, net, and drag; or by those things signified by them, the arts and methods they used to subdue nations, conquer kingdoms, and bring them into subjection to them; they enlarged their dominions, increased their riches and revenues, and had plenty of everything that was desirable for food and raiment, for pleasure and profit; or to gratify the most unbounded ambition, having everything that heart could wish for and desire: the allusion is to making sumptuous feasts, and rich banquets, on occasion of victories obtained.
