(20) To sharpen every man his share, and his coulter.--Porsenna, we read, in the time of the wars of the Republic, allowed the Romans iron implements for agriculture only. Coulter.--In Isaiah 2:4, Joel 3:10, this word is rendered "ploughshares "; so most of the older versions. We cannot now with any precision distinguish between these two implements of tillage.

And his mattock.--Jerome renders the Hebrew word here by "hoe" (sarculum). It was probably a kind of heavy hoe, used for turning up the ground.

Verse 20. - The Israelites went down to the Philistines. I.e. to their land. This could only have applied to the districts near the Philistines, unless we suppose that they set up forges also at their garrisons. To sharpen. The verb chiefly refers to such work as required an anvil and hammer. As regards the implements, not only do the versions disagree in their renderings, but the Septuagint has a very curious different reading, to the effect that at harvest time the Israelites had to pay the Philistines three shekels for repairing and whetting their tools. The share is more probably a sickle. The coulter is certainly a ploughshare, as rendered in Isaiah 2:4; Joel 3:10. Of the ax there is no doubt; and the mattock is a heavy hoe for turning up the ground, as spades for that purpose are scarcely anywhere used, except in our own country.

13:15-23 See how politic the Philistines were when they had power; they not only prevented the people of Israel from making weapons of war, but obliged them to depend upon their enemies, even for instruments of husbandry. How impolitic Saul was, who did not, in the beginning of his reign, set himself to redress this. Want of true sense always accompanies want of grace. Sins which appear to us very little, have dangerous consequences. Miserable is a guilty, defenceless nation; much more those who are destitute of the whole armour of God.But all the Israelites went down to the Philistines,.... Were obliged to go into Palestine, into some one or other of the cities of the Philistines, or to their garrisons, where the trade of a smith was exercised:

to sharpen every man his share, and his coulter; which are the parts of the plough made of iron, with which the earth is cut and thrown up:

and his axe and his mattock; or pick axe; with the one wood is felled and cut, and with the other stones are dug; and each of these for their several uses needed sharpening; and when they did, they were obliged to go to the Philistines to have them done, they having no smiths among them.
