'Wool' in the Bible

“For their mother has played the prostitute;She who conceived them has acted shamefully,For she said, ‘I will pursue my loversWho give me my food and my water,My wool and my flax, my oil and my [refreshing] drinks.’

“Therefore, I will return and take back My grain at harvest timeAnd My new wine in its season.I will also take away My wool and My flaxGiven to cover her nakedness.
