Exactly how many sons of Gideon were slain by Abimelech
In Judges 8 vs 30, it was mentioned that Gideon had 70 sons and one born to him by his concubine. Total is 71. But, one of them Abimelech killed the rest seventy save one (Jotham) who escaped being killed. The total killed should then be 69. But it was recorded in Chapter 9 vs 5, 24 and 56 that seventy of them were slain.
