45 Abimelech fought against the city all that day; and he took the city, and killed the people who were therein: and he beat down the city, and sowed it with salt.
*Minor differences ignored. Grouped by changes, with first version listed as example.
Sowed it with salt - Expressing by this action his hatred, and his wish, that when utterly destroyed as a city, it might not even be a fruitful field. Salt is the emblem of barrenness (see the marginal references).
And sowed it with salt - Intending that the destruction of this city should be a perpetual memorial of his achievements. The salt was not designed to render it barren, as some have imagined; for who would think of cultivating a city? but as salt is an emblem of incorruption and perpetuity, it was no doubt designed to perpetuate the memorial of this transaction, and as a token that he wished this desolation to be eternal. This sowing a place with salt was a custom in different nations to express permanent desolation and abhorrence. Sigonius observes that when the city of Milan was taken, in a.d. 1162, the walls were razed, and it was sown with salt. And Brantome informs us that it was ancient custom in France to sow the house of a man with salt, who had been declared a traitor to his king. Charles IX., king of France, the most base and perfidious of human beings, caused the house of the Admiral Coligni (whom he and the Duke of Guise caused to be murdered, with thousands more of Protestants, on the eve of St. Bartholomew, 1572) to be sown with salt! How many houses have been since sown with salt in France by the just judgments of God, in revenge for the massacre of the Protestants on the eve of St. Bartholomew! Yet for all this God's wrath is not turned away, but his hand is stretched out still.
And Abimelech fought against the city all that day; and he took the city, and slew the people that [was] therein, and beat down the city, and sowed it with (o) salt.
(o) That it should be unfruitful and never serve to any use.
And Abimelech fought against the city all that day,.... By throwing stones or arrows into it:
and he took the city; it was surrendered to him, not being able to stand out against his forces:
and slew the people that was therein; all but those that were of his own family and his friends; all that had taken up arms against him, or had shown their dislike of his government, and were his enemies:
and beat down the city; the houses in it, and walls of it, though it was his native place:
and sowed it with salt; not to make it barren, for he would rather then have sowed the field, though this would not have had any effect of that kind, for any time at least; but to show his detestation of it, because of the ill usage he had met with, and as a token of its perpetual destruction, to which he devoted it, determining that if it was in his power it should never be rebuilt; but it was hereafter, and became again a very flourishing city in Jeroboam's time. Thus the Emperor Frederic Barbarossa, in the year 1162, when he took Milan, not only ploughed it up, but sowed it with salt; and in memory of it there is a street in it, now called "la contrada della Sala" (n): besides, Abimelech did this to deter other cities from rebelling against him; for if he so used his own city, more severely, if possible, would he use others.
(n) Sigonius de regn. Ital. l. 13, & 14.
Thus Abimelech fought all that day against the city and took it; and having slain all the people therein, he destroyed the city and strewed salt upon it. Strewing the ruined city with salt, which only occurs here, was a symbolical act, signifying that the city was to be turned for ever into a barren salt desert. Salt ground is a barren desert (see Job 39:6; Psalm 107:34).
With salt - In token of his desire of their utter and irrecoverable destruction.
