Psalms 26:6

6 I awash my hands in innocence
and go around your altar, O Lord,

Isaiah 1:16-18

16 bWash yourselves; make yourselves clean;
remove the evil of your deeds from before my eyes;
ccease to do evil,
17learn to do good;
dseek justice,
correct oppression;
ebring justice to the fatherless,
plead the widow’s cause.
18 Come now, flet us reason
Or dispute
together, says the Lord:
though your sins are like scarlet,
they shall be as hwhite as snow;
though they are red like crimson,
they shall become like wool.

Hebrews 10:22

22let us draw near with a true heart in full assurance of faith, with our hearts isprinkled clean jfrom an evil conscience and our bodies kwashed with pure water.
