Leviticus 5:4-6

CKJV_Strongs(i)
  4 H5315 Or if a soul H7650 swear, H981 pronouncing H8193 with his lips H7489 to do evil, H3190 or to do good, H120 whatever it be that a man H981 shall pronounce H7621 with an oath, H5956 and it be hid H3045 from him; when he knows H816 of it, then he shall be guilty H259 in one of these.
  5 H816 And it shall be, when he shall be guilty H259 in one H3034 of these things, that he shall confess H2398 that he has sinned in that thing:
  6 H935 And he shall bring H817 his trespass offering H3068 unto the Lord H2403 for his sin H2398 which he has sinned, H5347 a female H6629 from the flock, H3776 a lamb H8166 or a kid H5795 of the goats, H2403 for a sin offering; H3548 and the priest H3722 shall make an atonement H2403 for him concerning his sin.
