In the same day also will I punish all those that leap on the threshold,.... Not in a ludicrous way, who, by dancing and leaping, made sport for persons, and brought their masters much gain, as the damsel possessed with a spirit of divination did, Ac 16:16 rather, that entered rashly and irreverently into the house of God; or else in an idolatrous way, who, when they went into an idol's temple, did not tread upon the threshold, but leaped over it, as the priests of Dagon, after the fall of that idol on the threshold, 1Sa 5:4.
So the Targum,"and I will visit all those that walk in the laws (or according to the customs) of the Philistines;''whose idol Dagon was: but it seems better to interpret it of such, who, seeing houses full of good things, in a rude, bold, insolent manner, thrust themselves, or jumped into them, and took away what they pleased; or when they returned to their masters' houses with their spoil, who set them on, and encouraged them in these practices, leaped over the threshold for joy of what they had got, as Aben Ezra observes; which agrees with what follows:which fill their masters' houses with violence and deceit; that is, with goods got by rapine and force, and by fraudulent ways and methods: this is to be understood of the servants of great men, who, to feed the ambition and avarice of their masters, used very oppressive methods with inferior persons to get their substance from them, and gratify their masters.
