'Washed' in the Bible

Moses brought Aaron and his sons and washed them with water.

washed the internal organs and the thigh with water, and then burned the entire ram on the altar as a whole burnt offering, a pleasing aroma of an offering made by fire to the LORD, just as the LORD had commanded him.

washed the internal organs and thighs, and incinerated them on the altar, along with the whole burnt offering.

Furthermore, anything on which they fall when they're dead becomes unclean, whether on an article of wood, clothing, skin, or a sack. And any vessel used for any work is to be washed in water, because it has become unclean until evening.

Then the priest is to examine it after the contagion has been washed. If the contagion hasn't changed in appearance, even though the contagion hasn't spread, it's unclean. Incinerate it. It's a fungal infection, especially if the infection is on its exposed side.

"If the priest examines the item and determines that the contagion has become dull after it has been washed, tear it away from the garment, leather, woven material, or knitted material.

Then the clothing (whether it is woven or knitted material) or any article made of leather that you've washed, if the contagion has been removed from it and it's washed a second time, then it's clean.

On the seventh day, he is to shave the hair on his head, chin, back, and eyebrows. After he has shaved all his hair, washed his clothes, and bathed himself with water, then he will be clean."

Every garment (including leather) on which the semen is found is to be washed with water, and it will remain unclean until evening.
