Ezekiel 25:6
For thus saith the Lord GOD; Because thou hast clapped thine hands, and stamped with the feet, and rejoiced in heart with all thy despite against the land of Israel; For thus saith the Lord GOD; Because thou hast clapped thine hands, and stamped with the feet, and rejoiced in heart with all thy despite against the land of Israel;
The verse stands among the prophecies against foreign nations in Ezekiel 25-31, including Ammon and Moab, whose fulfillment is evident. In it the heart is the seat of feelings and emotions, and Ammon is described as rejoicing inwardly with contempt against Israel. It is an instance of nephesh applied to a person's emotional life, where rejoicing in heart with despite means hostile contempt felt as an emotion.
The verse portrays Ammon expressing hostile contempt and rejoicing over Israel's calamity by clapping hands, stamping feet, and rejoicing in heart. That malicious clapping, stamping, and rejoicing took place when Israel lay desolate and in disgrace and humiliation, when Jerusalem and the sanctuary had been brought low and devastated.
This clapping, stamping, and malicious rejoicing with despite against the land of Israel is stated as the reason for God's condemnation, judgment, and declared punishment of Ammon. The Lord's judgment for celebrating Judah's desolation fell upon the surrounding nations and upon those who mocked devastated Jerusalem. For Ammon that judgment meant its capital Rabbah would become a place for camels and flocks.
Delight in the suffering and disgrace of God's people is an offense against God's work. The verse also warns that failure to hate bloodshed brings bloodshed upon the offender, teaching that the spirit of war must be subdued and that taking part in war, if required, must be treated as a painful duty rather than cherished.
