Goats are frequently raised by the nomadic peoples of the modern and ancient Near East. One product from the goats is their milk, a common food staple. This word is also related to the word hhelev (Strongs #2459) meaning fat, because of the high fat content in goat’s milk. The milk was also turned into cheese, or more correctly curds, by separating out the water in the milk.
