Both before and after a meal, a pious Jew ritually washes his hands, uttering a special blessing. On one of these two occasions he is worshiping God, by promoting the divine union of Son and Daughter; but on the other he is worshiping Satan, who likes Jewish prayers and ritual acts so much that when he is offered a few of them it keeps him busy for a while and he forgets to pester the divine daughter.
