thick cloth

Boyd’s Bible Dictionary:

Skins first supplied the place of cloth. Art of weaving cloth early known (Ex. 35:25. Judg. 5:30).

Concise Bible Dictionary:

The two Hebrew words translated “cloth,” beged and simlah, are also translated “garments,” and do not explain of what it was composed nor how wrought. In Exodus 31:10 beged is used for “cloths of service,” and in Numbers 4:6-13 for the “cloth of blue” that covered up the furniture when the tabernacle was removed. Simlah occurs in Deuteronomy 22:17 and 1 Samuel 21:9. The THICK CLOTH in 2 Kings 8:15 is makber. See LINEN.
