why is thomas in the bible called the twin
Thomas the Apostle The name Thomas (Koine Greek: Θωμᾶς) given for the apostle in the New Testament is derived from the Aramaic or Classical Syriac: ܬܐܘܡܐ‎ Toma, equivalently from Hebrew Teom, meaning "twin". The equivalent term for twin in Greek, which is also used in the New Testament, is Δίδυμος Didymos.
Abby and Brittany Hensel Abigail Loraine "Abby" Hensel and Brittany Lee Hensel (born March 7, 1990) are American dicephalic parapagus twins; in other words, they are conjoined twins, each of whom has a separate head, but whose bodies are joined. They are highly symmetric for conjoined twins, giving the appearance of having a single body without marked variation from normal proportions. In fact, several vital organs are doubled; each twin has a separate heart, stomach, spine, pair of lungs, and spinal cord.
