Deuteronomy 23:11

³⁸When the Pharisee saw it, he marveled that he had not first washed himself before dinner. ³⁹The Lord said to him, “Now you Pharisees cleanse the outside of the cup and of the platter, but your inward part is full of extortion and wickedness.

²⁶that he might sanctify her, having cleansed her by the washing of water with the word, ²⁷that he might present the assembly to himself gloriously, not having spot or wrinkle or any such thing, but that she should be holy and without defect.

⁹It shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows. He shall shave off all his hair. He shall wash his clothes, and he shall bathe his body in water. Then he shall be clean.

⁵Whoever touches his bed shall wash his clothes, and bathe himself in water, and be unclean until the evening.

²²let’s draw near with a true heart in fullness of faith, having our hearts sprinkled from an evil conscience and having our body washed with pure water,

⁵and from Jesus Christ, the faithful witness, the firstborn of the dead, and the ruler of the kings of the earth. To him who loves us, and washed us from our sins by his blood—

¹¹“I indeed baptize you in water for repentance, but he who comes after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you in the Holy Spirit.

²⁵Whoever carries any part of their carcass shall wash his clothes, and be unclean until the evening.

²Wash me thoroughly from my iniquity. Cleanse me from my sin.

⁹This is a symbol of the present age, where gifts and sacrifices are offered that are incapable, concerning the conscience, of making the worshiper perfect, ¹⁰being only (with foods and drinks and various washings) fleshly ordinances, imposed until a time of reformation.
