'Treachery' in the Bible

"Thus says all the congregation of Yahweh: 'What [is] this treachery that you have committed against the God of Israel by turning away today from following Yahweh, by building for yourselves an altar to rebel today against Yahweh?

Did not Achan son of Zerah commit treachery with devoted things, and wrath fell on all the congregation of Israel? {And he alone} did not perish because of his iniquity.'"

"Yahweh, God of gods! Yahweh, God of gods knows. And let Israel itself know, if [it was] in rebellion or treachery against Yahweh, do not spare us this day

Phinehas the priest, son of Eleazar, said to the descendants of Reuben, Gad, and Manasseh, "Today we know that Yahweh [is] among us, because you have not committed this treachery against Yahweh. Therefore you have rescued the {Israelites} from the hand of Yahweh."
