Numbers 5:27
11Then the Lord said to Moses,
12“Speak to the Israelites and say to them: ‘If a man’s wife goes astray and is unfaithful to him
13so that another man has sexual relations with her, and this is hidden from her husband and her impurity is undetected (since there is no witness against her and she has not been caught in the act),
14and if feelings of jealousy come over her husband and he suspects his wife and she is impure—or if he is jealous and suspects her even though she is not impure—
15then he is to take his wife to the priest. He must also take an offering of a tenth of an ephah
c of barley flour on her behalf. He must not pour olive oil on it or put incense on it, because it is a grain offering for jealousy, a reminder-offering to draw attention to wrongdoing.
16“ ‘The priest shall bring her and have her stand before the Lord.
17Then he shall take some holy water in a clay jar and put some dust from the tabernacle floor into the water.
18After the priest has had the woman stand before the Lord, he shall loosen her hair and place in her hands the reminder-offering, the grain offering for jealousy, while he himself holds the bitter water that brings a curse.
19Then the priest shall put the woman under oath and say to her, “If no other man has had sexual relations with you and you have not gone astray and become impure while married to your husband, may this bitter water that brings a curse not harm you.
20But if you have gone astray while married to your husband and you have made yourself impure by having sexual relations with a man other than your husband”—
21here the priest is to put the woman under this curse—
“may the Lord cause you to become a cursed among your people when he makes your womb miscarry and your abdomen swell. 22May this water that brings a curse enter your body so that your abdomen swells or your womb miscarries.”
“ ‘Then the woman is to say, “Amen. So be it.”

He also asked Moses to conduct a census of all Israelite males, but only starting at one month and older. -
Numbers 3:39-40
14The Lord said to Moses in the Desert of Sinai,
15“Count the Levites by their families and clans. Count every male a month old or more.”
16So Moses counted them, as he was commanded by the word of the Lord.

Exodus 21:22-25
22“And
if men struggle with each other and strike a woman with child so that she has a miscarriage, yet there is no
further injury, he shall surely be fined as the woman’s husband may demand of him; and he shall pay as the judges
decide.23“But if there is
any further injury, then you shall appoint
as a penalty life for life,
24eye for eye, tooth for tooth, hand for hand, foot for foot,
25burn for burn, wound for wound, bruise for bruise.

So basically, if a man causes a woman to have a miscarriage, it is only a fine. If the woman is injured, it's eye for eye/life for life.
