Halakhah su Deuteronomio 10:19

2. It is a positive commandment to believe in God's oneness, believing with complete faith that He is One, without contemporary. As it is said (Deuteronomy 6:4): "Hear, O Israel: the Lord is our God - the Lord is one!" This is the fundament of the faith. After the initial knowledge that there is one God who exists, one needs to belief with complete faith that He is one - in simple and ultimate unity, that He has no body, that the concepts which apply to a physical body do not apply to Him, that things which happen to a body cannot happen to Him, that he has no second, and that there is no power beside Him. This belief is obligatory upon us in all times and all places, to males and females.

The laws of the commandment are, for example, the many [prohibitions] that they, may their memory be blessed, warned us about; that they made known to us - in order to warn us more about the thing - that the Torah warned about it in twenty-one (and see the Lemberg edition, that reads, twenty-four) places (Bava Metzia 39b); that they also wrote to strengthen the commandment, that with the same expression that we were commanded about the love of the Omnipresent, we were [also] commanded about the love of the convert - as with the Omnipresent, it is written (Deuteronomy 6:5), "And you shall love your God"; and with the convert, it is written (Deuteronomy 10:19), "And you shall love the convert." And many things like this are in Midrash and in a few places in the Gemara (see Tur, Choshen Mishpat, 307).

The Lord Himself is described as evidencing concern for the welfare of the proselyte, as loving him "in giving him bread and clothing" (Deut. 10:18). The Torah specifically commands us to mirror this divine love in our actions and emotions: "And you shall love the proselyte, for you were proselytes in the land of Egypt" (Deut. 10:19).
