Who shall ascend the hill of the Lord? And who shall stand in his holy place? Those who have clean hands and pure hearts, who do not lift up their souls to what is false, and do not swear deceitfully. They will receive blessing from the Lord, and vindication from the God of their salvation. Such is the company of those who seek him, who seek the face of the God of Jacob. (Psalm 24: 3-6)

Most religious traditions have cleansing rituals. It can often be as simple as washing hands before entering a place of worship.

Hebrew has several words that can be translated as clean. Above those who have naqiy hands and barar hearts will receive God's blessing. Each can mean clean. Neither necessarily imply a ritual, as with taher.

Naqiy has implications for being innocent or empty. Barar is suggestive of having been purged and polished. Sincerity of intention and innocent actions are both important.

I cannot do this cleaning myself. My intentions are often confused. My actions are prone to accident or worse.

For me cleansing is not possible before coming to God. Any cleansing is the result of being with God.
