Sahih International
If they are expelled, they will not leave with them, and if they are fought, they will not aid them. And [even] if they should aid them, they will surely turn their backs; then [thereafter] they will not be aided.
Muhsin Khan
Surely, if they (the Jews) are expelled, never will they (hypocrites) go out with them, and if they are attacked, they will never help them. And if they do help them, they (hypocrites) will turn their backs, so they will not be victorious.
Pickthall
(For) indeed if they are driven out they go not out with them, and indeed if they are attacked they help them not, and indeed if they had helped them they would have turned and fled, and then they would not have been victorious.
Yusuf Ali
If they are expelled, never will they go out with them; and if they are attacked (in fight), they will never help them; and if they do help them, they will turn their backs; so they will receive no help.
Shakir
Certainly if these are driven forth, they will not go forth with them, and if they are fought against, they will not help them, and even if they help-them, they will certainly turn (their) backs, then they shall not be helped.
Dr. Ghali
Indeed in case they are driven out, they will not go out with them; and indeed in case they are fought against, they will not vindicate them; and indeed in case they vindicate them, indeed they will definitely turn their backs; thereafter they will not be vindicated.
