Pleko (πλέκω) means to braid, weave, plait, or twist together. In the NT it appears exclusively in the passion narratives, where Roman soldiers wove a crown of thorns and placed it on Jesus' head.
All three Synoptic Gospels record the soldiers weaving a crown of thorns for Jesus (Matthew 27:29; Mark 15:17; John 19:2). This act was cruel mockery — a parody of the emperor's laurel crown forced onto the One they mocked as 'King of the Jews.' Yet in God's sovereign irony, the crown of thorns became one of the most powerful symbols in Christian theology. The thorns — which first appeared as part of the curse in Genesis 3:18 — were literally pressed onto the brow of the One who came to bear the curse (Galatians 3:13). What soldiers intended as humiliation, God ordained as a visible sign that Christ was absorbing the consequences of the Fall.
