Three things to consider scripturally:
The original Hebrew word translated "soul" is neʹphesh, which literally means "breathing creature"
This is in harmony with Adam's creation described in Genesis 2:7
7 And Jehovah God went on to form the man out of dust from the ground and to blow into his nostrils the breath of life, and the man became a living person.*
Or “soul.” Hebrew, neʹphesh, which literally means “a breathing creature.”
3. The child before birth breathes through his/her mother through the placenta and the umbilical cord. Showing that the baby before birth is a breather, therefore he/she is a soul, is made clear in Exodus 21:22, 23.
22 “If men should struggle with each other and they hurt a pregnant woman and she gives birth prematurely* but no fatality results, the offender must pay the damages imposed on him by the husband of the woman; and he must pay it through the judges. 23 But if a fatality does occur, then you must give life for life,*
So according to the Mosaic Law, if a preborn child dies due to the actions of another person, that person's life must be forfeit.
Christians are not under the Mosaic Law which was given to the Israelites, but that Law does let us know how God values the life of a child before he/she is born. The two scriptures here also show that a "soul" is not something that someone "gets" - we ARE souls.
