The gemara in the Jerusalem Talmud Bava Batra (cited here) refers to a collective set of commandments called "מתן שכרה בצידה", which I believe can be loosely translated as "reward given on the side" and I parenthetically add, (in this world). It is my understanding that there are 2 mitzvot referenced in the Torah that can be categorized as such, namely שילוח הקו (sending away the mother bird) and כיבוד אב ואם,(honoring one's father and mother) which both come with a reward of אריכת ימים, which is simply translated as, "length of days". Can someone inform me if there are other mitzvot that are considered to fall under the category of "מתן שכרה בצידה" besides the 2 mitzvot referenced above and what they are along with their respective rewards?
