'Symbols' in the Bible

It shall be for a sign on your hand, and for symbols between your eyes: for by strength of hand Yahweh brought us forth out of Egypt."

You shall bind them for a sign on your hand, and they shall be for symbols between your eyes.

Therefore you shall lay up these my words in your heart and in your soul; and you shall bind them for a sign on your hand, and they shall be for symbols between your eyes.
