Psalms 78:53

They feared not. But it is said that they were sore afraid, Exodus 14:10. Answ.

1. They were afraid at first, but after Moses had encouraged them they grew bold and secure; one evidence whereof was, that they confidently went into the middle of the sea, and passed between the vast heaps of water which were on both sides of them.

2. The meaning may be that they had no just cause to fear; for men are oft said to do not only what they actually do, but also what they ought to do, as Zechariah 1:6, Zechariah 2:7, &c.
