“Now, remember that you were a slave in the land of Egypt” (Dt.15:15).
Just as, in Egypt, I repeatedly provided for you,
so must you, too, repeatedly provide for him [your freed slave];
just as, in Egypt, I gave to you with an open hand,
so must you, too, give to him with an open hand.
And, similarly, He says:
“There are dove’s wings plaited with silver” (Ps.68:14)—
this refers to Israel’s despoiling [of the Egyptians] in Egypt.
“And her limbs with engraved gold” (Ps.68:14)—
this refers to the despoiling [of Egypt] at the Sea.
“We will make for you bracelets of gold” (Song 1:11)—
this refers to the despoiling of Egypt in the Sea.
“With studs of silver” (Song1:11)—
this refers to the despoiling [of the Egyptians] in Egypt.2
“Therefore, I command you concerning this matter today” (Dt.15:15)—
during the day you may pierce the ear
[of the Hebrew slave who wishes to remain enslaved];
but you may not pierce the ear at night.
