An Illustration from the life of David
David is well known as a shepherd. An interesting episode from his life is recorded in 1 Samuel 25.
4 David heard in the wilderness that Nabal was shearing his sheep.
5 So David sent ten young men. And David said to the young men, “Go up to Carmel, and go to Nabal and greet him in my name.
6 And thus you shall greet him: ‘Peace be to you, and peace be to your house, and peace be to all that you have.
7 I hear that you have shearers. Now your shepherds have been with us, and we did them no harm, and they missed nothing all the time they were in Carmel. (1 Sam. 25:4-7 ESV)
A common expression among the Jews was that goats were kept for milk, hens for eggs, and sheep for wool. The wool could be converted into clothing for the family. I have seen Bedouin milking sheep.
The wool was converted to yarn, primarily by the women of the village, to be used in the making of clothing for the family.
