Chasidut su Salmi 85:14

"Justice goes before Him, as He sets out on His way." (Psalms 85:14) -- There is a moral teaching here. There are some people who, on their way to fulfil the mitzvah of prayer or some such thing, stop to speak to other people. Even though they afterwards go on to the mitzvah, they have transgressed in not having run with passion, and their punishment after their death will be similar in nature. We know from several books that [after death] one passes over a river on a very narrow bridge, and this is considered as difficult suffering, for one has fear and trembling and needs to run very fast. This is the only way, on a very narrow bridge, to run fast. And then in the middle of the bridge, the Holy One sends an interrupting angel! And this is the very same angel that was created from that mitzvah that was interrupted and caused pain to this angel. From the thought that one had at home, intending to perform the mitzvah, a soul was created for the angel, and in actually performing the mitzvah, a body was created. But since one delayed the creation of that body, tarrying along the way and speaking to people, this angel comes to delay one, and not allow one to run, and this will be very frightening. This is the meaning of "Justice goes before Him," -- the simple meaning is that all one's mitzvot walk before one after death. But when one is careful to go quickly and passionately when going to perform a mitzvah or to the synagogue, and not with laziness, "He sets out on His way" and doesn't interrupt the person crossing the river.
