Exodus 21:4

21:4 If his master gave ¹  him a wife, and she bore sons or daughters, the wife and the children will belong to her master, and he will go out by himself.

Exodus 22:3

22:3 If the sun has risen on him, then there is blood guilt for him. A thief ²  must surely make full restitution; if he has nothing, then he will be sold for his theft.

[21:4]  ¹ sn The slave would not have the right or the means to acquire a wife. Thus, the idea of the master’s “giving” him a wife is clear – the master would have to pay the bride price and make the provision. In this case, the wife and the children are actually the possession of the master unless the slave were to pay the bride price – but he is a slave because he got into debt. The law assumes that the master was better able to provide for this woman than the freed slave and that it was most important to keep the children with the mother.

[22:3]  ² tn The words “a thief” have been added for clarification. S. R. Driver (Exodus, 224) thinks that these lines are out of order, since some of them deal with killing the thief and then others with the thief making restitution, but rearranging the clauses is not a necessary way to bring clarity to the paragraph. The idea here would be that any thief caught alive would pay restitution.
