And where is it seen that one blessing was given to Israel, which encompasses all blessing? In (Koheleth 5:10) "The lover of silver will not be sated with silver, and he who loves (it) in profusion will have no produce," and (Ibid. 8) "the profit of the earth (i.e., the field) is over all. The king is subservient to the field." A king who rules over treasures of silver and gold is subservient to the produce of the field — whence we see that the blessing given to Israel encompasses all others.
