The pillow of goat's hair which Michal put for a bolster (1 Samuel 19:13) was probably a curtain to protect the sleeper from mosquitoes, or a counterpane, with which sleepers in the East protect the head and face. Κebir means something woven, from kaabar "to weave." The indefinite article implies it was one of the articles of regular use, as a counterpane or veil woven of goat's hair to cover the head and face while sleeping.
