Ezekiel 36:24-26

36:24 “‘I will take you from the nations and gather you from all the countries; then I will bring you to your land. 36:25 I will sprinkle you with pure water ¹  and you will be clean from all your impurities. I will purify you from all your idols. 36:26 I will give you a new heart, and I will put a new spirit within you. I will remove the heart of stone ²  from your body and give you a heart of flesh. ³ 

[36:25]  ¹ sn The Lord here uses a metaphor from the realm of ritual purification. For the use of water in ritual cleansing, see Exod 30:19-20; Lev 14:51; Num 19:18; Heb 10:22.

[36:26]  ² sn That is, a heart which symbolizes a will that is stubborn and unresponsive (see 1 Sam 25:37). In Rabbinic literature a “stone” was associated with an evil inclination (b. Sukkah 52a).

[36:26]  ³ sn That is, a heart which symbolizes a will that is responsive and obedient to God.
