The bible does not explicitly mention Christmas trees or the act of decorating a tree. However, there are several passages in the Old Testament that reference the use of evergreen trees or branches as symbols of everlasting life or as offerings to God. The Christmas tree, as we know it today, is a tradition that developed in the 16th century in Germany, where people would decorate evergreen trees with candles and other decorations to represent the birth of Jesus Christ. The practice was later adopted by other countries and has become a beloved symbol of the holiday season.
