 That's why God gave us this verse to take a bath in, to get our feet clean that Jesus did in John chapter 13, clean the disciples' feet. When we go to 1 John 1, 9 and confess our sin, we get our feet cleansed from sin. What a wonderful way to live. But as far as that word repent goes, three different words, metanoia, metamelomai, and metanoeo.
