parsha bit: B'shalach

"Speak to the children of Israel and tell them to go forth." When the Israelites found themselves at the sea of reeds, with Paro's army bearing down on them, Moshe prayed to God for guidance. Rabbi Eliezer says that God said to him: there is a time for brevity and a time for length. My children are threatened: quit talking to me and tell them to go forth! (Exodus Rabbah 21:8)
