The Bible consistently equates the unborn with a child, baby, or full human being, attributing personhood from conception.

In Luke 1 Elizabeth is 6 months pregnant when her unborn reacts to Mary’s greeting:

41 When Elizabeth heard Mary’s greeting, the baby leaped inside her. Elizabeth was filled with holy spirit 42 and cried out, “How blessed you are among women, and how blessed is your baby! 43 Why am I so honored that the mother of my lord would visit me? 44 As soon as I heard your greeting, my baby jumped for joy inside me. 45 How blessed you are for believing that what was spoken to you by the Lord will be fulfilled.”

The Greek word used here is brephos, a term employed interchangeably for the unborn and newborn. The same word appears in Luke 2:12, 16 for the newborn Jesus (“You will find a brephos wrapped in cloths…”) and in Acts 7:19 for exposed infants. This linguistic consistency underscores that Scripture makes no categorical distinction between the unborn and born baby—both are understood to be human persons.

A parallel appears in the Septuagint (LXX), the ancient Greek translation of the Old Testament. In Genesis 25:22 Rebekah’s twins in her womb are described: “The children struggled together within her.”

The Greek word translated “struggled” is the same Greek verb (eskirtēsanas) as in Luke 1:41, 44 for John’s movement in the womb. Furthermore, both Esau and Jacob are called paidia (another Greek word for “children”) even before birth. Their prenatal struggle is treated as personal interactions by God Himself when he says to Rebekah:

25:23 “Two nations are in your womb, and two peoples will be separated from within you. One people will be stronger than the other, and the older will serve the younger.” 25:24 When the time came for Rebekah to give birth, there were twins in her womb.

Other biblical examples of the unborn regarded as a child, a human life include:

• Exodus 21:22–25 — the “life for life” principle applies when harm comes to a pregnant woman and her unborn, showing that human life bears equal moral weight to that of a born human person.
• Psalm 139:13–16 — David describes God as the one who “knit me together in my mother’s womb,” noting that all his “days were ordained” before he was born.
• Jeremiah 1:5 — God says to the prophet: “Before I formed you in the womb, I knew you.”

Historical Addendum:

Before the modern medical era, the term quickening referred to the first time a mother felt her baby move in her womb—a clear sign of human life. As defined in John Bouvier’s Law Dictionary (1839):

“The motion of the fetus, when felt by the mother, is called quickening, and the mother is then said to be quick with child. This happens at different periods of pregnancy in different women, and in different circumstances, but most usually about the 15th or 16th week after conception.”

This concept goes back to Thomas Aquinas who, working within the limited biological knowledge of the 13th century, proposed that the “rational soul [a human person]” was infused at the moment of quickening. English Common Law adopted this view, recognizing legal protection for the unborn child once movement was perceived.

Later, as biblical and scientific understanding advanced, it became clear that life and personhood begin not at quickening but at conception. This conviction shaped early American thought as well—reflected in the Founding Fathers’ affirmation of the self-evident truths in the Declaration of Independence: the right to “Life, Liberty, and the pursuit of Happiness.”

Scripture, supported by moral and historical tradition, affirms the sanctity and personhood of human life from conception, not merely from the moment of perception or motion.
