Malchus was an agricultural worker in the neighbourhood of Antioch, and from his youth his whole spirit was directed towards God. The Arabs took him for a slave, and while he was in slavery they forced him to take a negress to wife. However, he brought her to the Christian faith and lived with her as a brother with his sister. They conspired together and escaped from slavery, but the Arabs nearly recaptured them. They hid in a cave in which they saw a lioness with her cubs, and were very greatly afraid. But God preserved them; the lioness did not harm them but killed an Arab who tried to enter the cave and seize the runaways. Reaching his home country, Malchus gave his wife to a women's monastery and went himself to a men's monastery. He lived for many years, exercising himself in asceticism, and took his place among the inhabitants of heaven in the fourth century.
