...Another explanation. 'The LORD is my light and my help...' My light by the sea, as it says "...and it lit up the night..." (Exodus 14:20) And my help by the sea, as it says "...Stand by, and witness the deliverance which the LORD will work for you..." (ibid. v. 13) Whom should I fear? "But Moses said to the people, “Have no fear!" (ibid.) The LORD is the stronghold of my life, "The LORD is my strength and might..." (Exodus 15:2) Whom should I dread?

"Terror and dread descend upon them..." (ibid. v. 16) When evil men assail me, "As Pharaoh drew near..." (Exodus 14:10) To devour my flesh, "...My desire shall have its fill of them..." (Exodus 15:9) R' Shmuel bar Nachmani said: the wicked do not leave this world until they announce their own verdict upon themselves. This is what is written "I will pursue, I will overtake" (ibid.) It does not then say 'we will divide' but rather "I will divide the spoil" (ibid.) I will be divided.

It is they, my foes and my enemies, who stumble and fall, "Who hurled Pharaoh and his army into the Sea of Reeds..." (Psalms 136:15) From here forward Israel said 'Should an army besiege me...' meaning the army of Egypt, '...my heart would have no fear.' 'should war beset me, because of this would I be confident.' 'This' always refers to Torah, as it says "This is the Teaching..." (Deuteronomy 4:44) The rabbis explained this verse as referring to Rosh HaShanah and Yom Kippur. 'my light,' on Rosh Hashanah.

'And my help,' on Yom Kippur. 'When evil men assail me,' this refers to the idolaters. 'To devour my flesh,' when they come to accuse Israel and say before the Holy One: these (meaning themselves) are idolaters and those (meaning Israel) are idolaters as well! 'my foes and my enemies,' the numerical value of the letters of hasatan (the accuser) is 364. Every day of the year he has the authority to make accusations, except on Yom Kippur (and Rosh Hashanah).

For this reason Israel said 'Should an army besiege me,' meaning the idolatrous nations, 'my heart would have no fear.' 'Should war beset me, because of this would I be confident,' R' Levi said: because of the bequest which you wrote in the Torah "Thus only shall Aaron enter the Shrine..." (Vayikra 16:3)
