Fire for a sacred purpose obtained otherwise than from the altar was called "strange fire" (Leviticus 10:1,2; Numbers 3:4 ).
The victims slain for sin offerings were afterwards consumed by fire outside the camp (Leviticus 4:12,21; 6:30; 16:27; Hebrews 13:11 ).
Torches were sometimes carried by the soldiers in battle (Judges 7:16 ).
God's word is also likened unto fire (Jeremiah 23:29 ). It is referred to as an emblem of severe trials or misfortunes (Zechariah 12:6; Luke 12:49; 1 Corinthians 3:13,15; 1 Peter 1:7 ), and of eternal punishment (Matthew 5:22; Mark 9:44; Revelation 14:10; 21:8 ).
The influence of the Holy Ghost is likened unto fire (Matthew 3:11 ). His descent was denoted by the appearance of tongues as of fire (Acts 2:3 ).
