Who often comes under attack instead of false teachers?
Those with the truth often come under attack instead of false teachers. The context states that instead of false teachers being bombarded, it is frequently those with the truth who come under attack, as when the speaker was wrongly accused and bombarded with false accusations that should have been reserved for false teachers.
Les explains that the accusations being hurled at the speaker should have been reserved for false teachers, but it was the other way around. Instead of the false teachers being bombarded, those with the truth come under attack. The speaker suffered privation after privation and was accused of not bringing the truth because he did not agree with the Judaizers in Jerusalem and was no longer working hand in glove with Peter and the eleven. He proclaimed something they knew nothing of, so he was bombarded with false accusations that should have been directed at false teachers.
