from evil.
3: But God is faithful, who will strengthen and keep you from evil.
But the Lord is faithful. Though men cannot be trusted, God is faithful to his promises and his purposes. He may always be confided in; and when men are unbelieving, perverse, unkind, and disposed to do us wrong, we may go to him, and we shall always find in him one in whom we may confide.
Who shall stablish you, and keep you from evil. "Jn 17:16" Comp. "Eph 6:16".
The allusion is to the Evil One, or Satan, and the meaning is, that God would keep them from his wiles.
