'Unfaithful' in the Bible

The Israelites, however, were unfaithful regarding the things set apart for destruction. Achan son of Carmi, son of Zabdi, son of Zerah, of the tribe of Judah, took some of what was set apart, and the Lord’s anger burned against the Israelites.

“Thus says the whole congregation of the Lord, ‘What is this unfaithful act which you have committed against the God of Israel, turning away from following the Lord this day, by building yourselves an altar, to rebel against the Lord this day?

Wasn’t Achan son of Zerah unfaithful regarding what was set apart for destruction, bringing wrath on the entire community of Israel? He was not the only one who perished because of his sin.’”

“The Mighty One, God, the Lord, the Mighty One, God, the Lord! He knows, and may Israel itself know. If it was in rebellion, or if in an unfaithful act against the Lord do not save us this day!

And Phinehas the son of Eleazar the priest said to the sons of Reuben and to the sons of Gad and to the sons of Manasseh, “Today we know that the Lord is in our midst, because you have not committed this unfaithful act against the Lord; now you have delivered the sons of Israel from the hand of the Lord.”
