11 And the priest shall offer the one for a sin offering, and the other for a burnt offering, and make an atonement for him, for that he sinned by the dead, and shall hallow his head that same day. 21 And the Levites were purified , and they washed their clothes; and Aaron offered them as an offering before the LORD; and Aaron made an atonement for them to cleanse them. 11 And Aaron said unto Moses, Alas, my lord, I beseech thee, lay not the sin upon us, wherein we have done foolishly , and wherein we have sinned . 40 And they rose up early in the morning, and gat them up into the top of the mountain, saying , Lo, we be here, and will go up unto the place which the LORD hath promised : for we have sinned . 27 And if any soul sin through ignorance, then he shall bring a she goat of the first year for a sin offering. 28 And the priest shall make an atonement for the soul that sinneth ignorantly , when he sinneth by ignorance before the LORD, to make an atonement for him; and it shall be forgiven him. 22 And they fell upon their faces, and said , O God, the God of the spirits of all flesh, shall one man sin , and wilt thou be wroth with all the congregation? 12 He shall purify himself with it on the third day, and on the seventh day he shall be clean : but if he purify not himself the third day, then the seventh day he shall not be clean . 13 Whosoever toucheth the dead body of any man that is dead , and purifieth not himself, defileth the tabernacle of the LORD; and that soul shall be cut off from Israel: because the water of separation was not sprinkled upon him, he shall be unclean; his uncleanness is yet upon him. 19 And the clean person shall sprinkle upon the unclean on the third day, and on the seventh day: and on the seventh day he shall purify himself, and wash his clothes, and bathe himself in water, and shall be clean at even. 20 But the man that shall be unclean , and shall not purify himself, that soul shall be cut off from among the congregation, because he hath defiled the sanctuary of the LORD: the water of separation hath not been sprinkled upon him; he is unclean. 7 Therefore the people came to Moses, and said , We have sinned , for we have spoken against the LORD, and against thee; pray unto the LORD, that he take away the serpents from us. And Moses prayed for the people. 34 And Balaam said unto the angel of the LORD, I have sinned ; for I knew not that thou stoodest in the way against me: now therefore, if it displease thee , I will get me back again . 19 And do ye abide without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify both yourselves and your captives on the third day, and on the seventh day. 20 And purify all your raiment, and all that is made of skins, and all work of goats' hair, and all things made of wood. 23 Every thing that may abide the fire, ye shall make it go through the fire, and it shall be clean : nevertheless it shall be purified with the water of separation: and all that abideth not the fire ye shall make go through the water. 23 But if ye will not do so , behold, ye have sinned against the LORD: and be sure your sin will find you out .
