Tehillim 78:51-53

Orthodox Jewish Bible

⁵¹ And struck all the bechor in Mitzrayim; the reshit (first fruit) of their strength in the ohalim of Cham;

⁵² But made His own people to go forth like tzon, and guided them in the midbar like an eder (flock).

⁵³ And He led them in safety, so that they had no terror; but the yam overwhelmed their oyevim.
