In the Choephoræ, Zeus is distinctly asked in the prayer of Agamemnon's children whence he can expect to obtain the sacrifice and honors which have been paid him by Orestes and Electra if he should suffer them to perish (Aisch., Choeph., 255). While in the Electra of Sophocles the converse motive of gratitude is appealed to: the god Apollon being desired to remember not what he may get, but what he already has got, from the piety of his supplicant (Soph. El., 1376—Schneidewin). And Jacob, who was a good hand at a bargain, makes his terms with Jehovah in a thoroughly business-like spirit. "_If_ God will be with me, and will keep me in this way that I go, and will give me bread to eat and raiment to put on, so that I come again to my father's house in peace; _then_ shall the Lord be my God: and this stone, which I have set up for a pillar, shall be God's house: and of all that thou shalt give me I will surely give the tenth unto thee." The adoption of Jehovah as Jacob's God being thus entirely dependent on the performance by that Deity of his share in the contract (Gen. xxviii. 20-22). Sometimes it is quaintly suggested that were the worshiper in the place of the god, _he_ would not neglect the interests of his devotee. Thus, the author of a hymn in the Rig-Veda-Sanhitâ, addressing the Gods of Tempest, exclaims: "If you, sons of Prisni, were mortals, and your worshiper an immortal, then never should your praiser be unwelcome, like a deer in pasture grass, nor should he go on the path of Yama" (R. V. S., vol. i. p. 65). Another unsophisticated poet gives the following hint to the god Indra, the Hindu Jupiter: "Were I, Indra, like thee, the sole lord of wealth, the singer of my praises should be rich in cattle" (S. V., i. 2. i. 3. p. 218). And the same god is asked elsewhere in the Veda: "When wilt thou make us happy? for it is just this that is desired" (S. V., i. 5. i. 3. p. 233). With equal plainness is the expectation of a _quid pro quo_ enunciated in one of the most ancient hymns, contained in the sacred books of the Parsees:—"Every adoration, O True One, consists in actions whereby one may obtain good possessions, full of security, and happiness round about" (F. G. vol. ii. p. 54.—Yama 51. i).
