Powtórzonego Prawa 7:9 Midrasz: Ein Yaakov (Glick Edition), Otzar Midrashim, Mekhilta DeRabbi Yishmael & Devarim Rabbah

(Ib. b) This will support R. Hamnuna who said in the name of Ulla: "A man is forbidden to salute his friend with Shalom (peace) while in the bath-house, for it is said (Jud. 6, 24.) And he called it 'God is Peace.'" According to your conclusion the word Hemnutha (faith) should also not be pronounced in a privy, because it is written (Deu. 7, 9.) The faithful God. And if thou wilt say that this is really the law, behold! Raba b. Mechasia in the name of R. Chama b. Guria who quoted Rab said: "Hemnutha (faith) is permitted to be pronounced in a privy." In the latter case it is different because the word (faith) is not used substantively but qualifiedly, for we explain it, The faithful God, whereas in the former case it is used substantively, as it is written He called it God is Peace.

"He commanded it as a testimony for a thousand generations" (Psalms 105:8), and it is written "And He performs kindness for two thousand [generations]" (Exodus 20:6). You find that one who performs Torah and mitzvot out of self-motivated love, "performs kindness for two thousand" - for those who love Him do so out of love. But one who performs out of fear - [it endures only] "for a thousand generations." Therefore it says "And for those who keep My commandments for a thousand generations" (Deuteronomy 7:9).

"I shall sing to the L–rd," who is trusty (Ibid. 7:9) "the trusty G–d, etc." (Ibid. 32:4) "… a G–d of trust, without wrong, etc."
