Is Ps 20, 23, 79, 91, 123. We also say the kaddish, which I said for ur father & my friends wife's father who seemed to pass away @ the same time. The theme of the kaddish is rather, the greatness of G-d who conducts the whole universe and especially His most favorite creature each of us with careful supervisionIn this prayer, we also pray for the Peace from the only One who can guarantee it and Peace between nations Peace between people and Peace of mindThis is in fact the only true comfort in the case of the loss of a loved one, that is, to be able to view the passing of the Beloved person from the perspective that the person's soul was gathered in so to speak, by the One who provided it in the first placeYou should find the kaddish on YouTube and listen to it, it is very beautifulShalo Ps 122:6
