What does the term burlap mean biblically?

In a biblical context, "burlap" often refers to coarse cloth made from jute or hemp, used for making sacks or coverings. It symbolizes mourning and repentance, as seen in passages where people don sackcloth (which may include burlap) as an outward expression of grief or humility before God. For example, during times of national lamentation or individual penitence, figures in The Bible would don sackcloth to signify their sorrow and desire for divine mercy.
