Deuteronomy 13:5

13:5 As for that prophet or dreamer, ¹  he must be executed because he encouraged rebellion against the Lord your God who brought you from the land of Egypt, redeeming you from that place of slavery, and because he has tried to entice you from the way the Lord your God has commanded you to go. In this way you must purge out evil from within. ² 

Deuteronomy 29:18

29:18 Beware that the heart of no man, woman, clan, or tribe among you turns away from the Lord our God today to pursue and serve the gods of those nations; beware that there is among you no root producing poisonous and bitter fruit. ³ 

¹ tn Heb “or dreamer of dreams.” See note on this expression in v. 1.

² tn Heb “your midst” (so NAB, NRSV). The severity of the judgment here (i.e., capital punishment) is because of the severity of the sin, namely, high treason against the Great King. Idolatry is a violation of the first two commandments (Deut 5:6-10) as well as the spirit and intent of the Shema (Deut 6:4-5).

³ tn Heb “yielding fruit poisonous and wormwood.” The Hebrew noun לַעֲנָה (la’anah) literally means “wormwood” (so KJV, ASV, NAB, NASB), but is used figuratively for anything extremely bitter, thus here “fruit poisonous and bitter.”
