“And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt.”
King James Version (KJV)
13:7 There shall no leavened bread be seen in all thy quarters - Accordingly the Jews usage was, before the feast of the passover, to cast all the leavened bread out of their houses; either they burnt it, or buried it, or broke it small, and threw it into the wind; they searched diligently with lighted candles in all the corners of their houses, lest any leaven should remain. The strictness enjoined in this matter was designed, To make the feast the more solemn, and consequently the more taken notice of by the children, who would ask, why is so much ado made? To teach us how solicitous we should be to put away from us all sin.
13:9 Upon thy hand, between thine eyes - Proverbial expressions; denoting things which are never out of our thoughts.
