A crown is a decorative, circular piece of jewelry worn on the head of rulers such as kings and queens. A crown is usually made of gold or silver. In Bible times, a crown was a symbol of a king's power and wealth. However, the Roman soldiers placed a crown of thorn branches on Jesus's head. This was meant to insult him and hurt him (see: Matthew 27:29-31).
In ancient times, winners of athletic contests were awarded a crown made out of olive branches (see: 1 Corinthians 9:25; 2 Timothy 2:5). People earned these crowns.
“To crown” someone means to put a crown on someone's head. “To crown” is also used as a metaphor. For example, to crown a person with glory and honor means to give a person glory and honor (see: Hebrews 2:7).
