Ezekiel 36:25

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.

Ezekiel 36:33

36:33 “‘This is what the sovereign Lord says: In the day I cleanse you from all your sins, I will populate the cities and the ruins will be rebuilt.

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.
