Halakhah su Deuteronomio 10:18

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 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).

“Love ye therefore the stranger” (Deut. 10:19). We are enjoined to love the individual who enters under the wings of the Divine Glory¹The proselyte. in order to fulfill all the commandments of the Torah. In thirty-six places the Torah cautioned us concerning love for the proselyte, not to wrong them²Baba Metzia 59b. either monetarily or through words. Greater is their love and more precious are they before God than His love for Israel.³Midrash Rabbah, ed. Horeb, Numbers, Chapter VIII, p. 43; also Mid-rash Tanhuma, ed. Horeb, Lech L’cho, p. 52. It is a parable of two people, one man loves the king and the other, the king loves him. Who is worthier? Surely, he whom the king loves. And thus is it comparable, Israel loves the Holy One, blessed be He, and the Holy One, blessed be He, loves the proselyte, for it is written, “And loveth the stranger, giving him food and raiment” (Deut. 10:18). For this reason it is incumbent upon us to love those whom the kings loves, and it is therefore written, “Love ye therefore the proselyte.”
