Part of this is loving your neighbor.
Neighbor is used 119 times in the OT.
Mar 12:28 And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all?

Mar 12:30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.

Mar 12:34 And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. And no man after that durst ask him any question.
John Gil writes about loving your neighbor in the OT.
Leviticus 19:34
But a stranger that dwelleth with you shall be unto you as one born among you,…. Especially if a proselyte of righteousness; for then he enjoyed the same privileges, civil and religious, the Israelites did, for there was one law for them both, Exo 12:49,
and thou shalt love him as thyself; and show it by doing all the good things for him they would have done for themselves in like circumstances:
for ye were strangers in the land of Egypt: and therefore knew what hardships such were exposed unto; and it became them to put on bowels of compassion, and show pity to those in a like condition, and particularly consider, as Jarchi suggests, that they were idolaters there also, and therefore ought not to upbraid strangers with their former idolatry:
I am the Lord your God; who showed kindness to them when strangers in Egypt, and had brought them out of that land, and therefore ought to obey his commands, and particularly in this instance.
Matthew Henry says…
IV. A charge to the Israelites to be very tender of strangers, Lev 19:33, Lev 19:34. Both the law of God and his providence had vastly dignified Israel above any other people, yet they must not therefore think themselves authorized to trample upon all mankind but those of their own nation, and to insult them at their pleasure; no, “Thou shall not vex a stranger, but love him as thyself, and as one of thy own people.” It is supposed that this stranger was not an idolater, but a worshipper of the God of Israel, though not circumcised, a proselyte of the gate at least, though not a proselyte of righteousness: if such a one sojourned among them, they must not vex him, nor oppress, nor over-reach him in a bargain, taking advantage of his ignorance of their laws and customs; they must reckon it as great a sin to cheat a stranger as to cheat an Israelite; “nay” (say the Jewish doctors) “they must not so much as upbraid him with his being a stranger, and his having been formerly an idolater.” Strangers are God’s particular care, as the widow and the fatherless are, because it is his honour to help the helpless, Psa 146:9. It is therefore at our peril if we do them any wrong, or put any hardships upon them. Strangers shall be welcome to God’s grace, and therefore we should do what we can to invite them to it, and to recommend religion to their good opinion. It argues a generous disposition, and a pious regard to God, as a common Father, to be kind to strangers; for those of different countries, customs, and languages, are all made of one blood. But here is a reason added peculiar to the Jews: “For you were strangers in the land of Egypt. God then favoured you, therefore do you now favour the strangers, and do to them as you then wished to be done to. You were strangers, and yet are now thus highly advanced; therefore you know not what these strangers may come to, whom you are apt to despise.”
Zec 8:16 These are the things that ye shall do; Speak ye every man the truth to his neighbour; execute the judgment of truth and peace in your gates:
Zec 8:17 And let none of you imagine evil in your hearts against his neighbour; and love no false oath: for all these are things that I hate, saith the LORD.
Gal 5:12 I would they were even cut off which trouble you.
Gal 5:13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
Gal 5:14 For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.
Gal 5:15 But if ye bite and devour one another, take heed that ye be not consumed one of another.
Gal 5:16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
Gal 5:17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
Gal 5:18 But if ye be led of the Spirit, ye are not under the law.
Gal 5:19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
Gal 5:20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
Gal 5:21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Gal 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
Gal 5:23 Meekness, temperance: against such there is no law.
Gal 5:24 And they that are Christ’s have crucified the flesh with the affections and lusts.
Gal 5:25 If we live in the Spirit, let us also walk in the Spirit.
