Befall - Vine's Expository Dictionary of New Testament Words
Befall
[ 1,,G1096, ginomai ]to become," is rendered "befell" in Mark 5:16; "hath befallen" in Romans 11:25, RV, for AV, "is happened to;" so the RV in 2 Corinthians 1:8; 2 Timothy 3:11.
[ 2,,G4819, sumbaino ]
lit., "to walk, or go together" (sun, "with," baino, "to go"), is used of things which happen at the same time; hence, "to come to pass, befall," Acts 20:19. In Acts 21:35, it is translated "so it was." See HAPPEN.
[ 3,,G4876, sunantao ]
"to meet with" (sun, "with," antao, "to meet"), is used much in the same way as sumbaino, of events which come to pass; "befall," Acts 20:22. See MEET.
Note: The phrase in Matthew 8:33, "what was befallen to them that were possessed with demons," is lit., "the things of the demonized."
