I'm afraid the question is meaningless due to a misunderstanding regarding the Hebrew verb system. Each verb has generally a "shoresh" (root) of 3 letters, and it can be conjugated in different "binyanim" (constructions), and in each it has a different meaning. for example the shoresh פקד means "to order" in binyan pa'al, "to lead" in binyan piel, and to deposit in binyan hif'il.. Some roots can be conjugated in pa'al and others not. As a general rule (with many irregularities) the pa'al serves for verbs without indirect object, or without a meaning of influencing something (I'm not sure about the professional terminology). For example to swim, to seat, to sleep..
