The bet also represents the 'house' of the son. <ref>[[Heb 3:6 But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.</ref> The name of the letter bet ב sounds like the word for ''house''. This meaning is consistent with the primary metaphor. Those who are the house of the son are filled with his word; the ones who received his revelation, and living water.
