Wales are second with two wins and two draws of their 10 matches so far - Israel have won three out of three.
Ben told us that 'every game is huge'
for Wales and the same could be said for Belgium, the pre-qualifying favourites who find themselves fourth at the moment.
Nacer Chadli, Mousa Dembele and Jan Vertonghen are in the Belgium squad to face third-placed Cyprus in Brussels and Jan has explained that Belgium are after two wins this week with Israel to follow on Tuesday. Kick-off is 7.45pm.
