Parshas Yisro

Rashi comments on וישמע יתרו, what did Yisro hear? He heard about Kriyas Yam Suf and the war with Amalek.
I once heard from R' Moshe Wolfson the following vort:
When Klal Yisroel left Mitzrayim, Doson and Avirom did not want to leave together with them. When they finally did leave, and they made it to the Yam Suf, the Yam had already gone back. Hashem then made a special Kriyas Yam Suf just for them.
Afterwards, since they had come late, they didn't make it into the Ananey Hakovod. Therefore the Amalekim started up with them, as Chazal say, that Amalek started with those who were out of the Anan. Still, Hashem allowed Klal Yisroel to win over Amalek in order to save them.
Yisro understood from these two events, that even if one comes late, and missed Kriyas Yam Suf, and missed being allowed into the Ananey Hakavod, Hashem will still make a special Kriyas Y"S for them, and a Melchemes Amalek to them.
Yisro understood that even if he had already been everywhere, and tried all the Avodah Zoras, it's never too late, and Hashem will do miracles to make sure that he can join Klal Yisroel
