Ezekiel 14:7-8

Anyone in Israel, including immigrants (Heb. ger, sojourners, resident aliens), who did not repent but continued to do what these elders had done and approached a false prophet for a message would receive judgment from the Lord. Note the emphasis on personal responsibility for sin throughout this passage (cf. Ezekiel 14:4). The Lord would oppose all such people making them object lessons to others of what happens when God’s people pursue idolatry. He would put them to death (cf. Leviticus 17:4; Leviticus 17:10; Leviticus 17:14; et al.). Then His people would know that He was God.

"In the Book of Ezekiel Israel’s idolatry was seen as the major cause for God’s judgment on His people." [Note: Dyer, "Ezekiel," pp. 1252-53.]
