שַׂק (saq)

The Hebrew noun saq refers to a coarse, mesh-like fabric made from goat or camel hair. Its primary function was practical: it served as durable material for sacks used to store grain and other goods. This utilitarian origin is evident in the Genesis narrative, where Joseph’s brothers discover their silver returned in their literal sacks (Genesis 42:27). The texture of the cloth, rough enough to allow liquids to drain through its weave, defined its physical character.

Over time, the same material took on a profound symbolic role in Israelite culture. Because it was uncomfortable and associated with poverty, wearing saq became the standard outward sign of deep mourning, humiliation, or repentance. When Jacob believed his son Joseph was dead, he tore his clothes and put on sackcloth (Genesis 37:34). Later prophets and kings like Isaiah and Hezekiah wore it to signal national crisis or personal contrition before God (Isaiah 20:2; 2 Kings 19:1). It was not merely clothing, but a visible language of grief.

Translators typically render saq as "sackcloth," preserving the connection to its original use. The word appears frequently in prophetic literature, such as Isaiah and Jeremiah, where it underscores the severity of judgment or the depth of sorrow. Its presence in Scripture highlights how physical discomfort was used to express spiritual reality.
