Leviticus 4:28

Or if his sin, which he hath sinned, come to his knowledge: then he shall bring his offering, a kid of the goats, a female without blemish, for his sin which he hath sinned.

if his sin, which he has sinned, is made known to him, then he shall bring for his offering a goat, a female without blemish, for his sin which he has sinned.

if his sin, which he hath sinned, be made known to him, then he shall bring for his oblation a goat, a female without blemish, for his sin which he hath sinned.

or his sin which he hath sinned hath been made known unto him, then he hath brought in his offering, a kid of the goats, a perfect one, a female, for his sin which he hath sinned,

When he becomes aware of the sin he has committed, he must bring an unblemished female goat as his offering for that sin.
