Yehezkiel 36:24-25

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.

[36:25]  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.
