"Two people are fighting; one accidentally pushes someone who is pregnant, causing a miscarriage. The text outlines the consequences: If only a miscarriage happens, the harm doer is obligated to pay financial damages. If, however, the pregnant person dies, the case is treated as manslaughter. The meaning is clear: The fetus is regarded as potential life, rather than actual life."
Misses the essential part, because elsewhere in Exodus...
Exodus 20:13 “You shall not murder.
From Deuteronomy, the consequences...
Deuteronomy 19:11 However, suppose a person hates someone else[x] and stalks him, attacks him, kills him,[y] and then flees to one of these cities. 12 The elders of his own city must send for him and remove him from there to deliver him over to the blood avenger[z] to die. 13 You must not pity him, but purge from Israel the guilt of shedding innocent blood,[aa] so that it may go well with you.
