Have we not all one {n} father? hath not one God created us? why do we deal treacherously every man against his brother, by profaning the covenant of {o} our fathers?

(n) The Prophet accuses the ingratitude of the Jews toward God and man: for seeing they were all born of one father Abraham, as God had elected them to be his holy people, they ought neither to offend God nor their brethren.

(o) By which they had bound themselves to God to be a holy people.

Wesley's Notes

2:10 One father - Abraham, or Jacob, with whom God made the covenant by which their posterity were made a peculiar people. Created us - The prophet speaks of that great and gracious work of God, creating them to be a chosen people. And so we Christians are created in Christ Jesus.

Scofield Reference Notes

Margin Have we not all one

Cf. Acts 17:24-29. In both instances the reference is to creation, not the new birth.

Jamieson-Fausset-Brown Bible Commentary

10-16. Reproof of those who contracted marriages with foreigners and repudiated their Jewish wives.

10. Have we not all one father?-Why, seeing we all have one common origin, "do we deal treacherously against one another" ("His brother" being a general expression implying that all are "brethren" and sisters as children of the same Father above (1Th 4:3-6), and so including the wives so injured)? namely, by putting away our Jewish wives, and taking foreign women to wife (compare Mal 2:14 and Mal 2:11; Ezr 9:1-9), and so violating "the covenant" made by Jehovah with "our fathers," by which it was ordained that we should be a people separated from the other peoples of the world (Ex 19:5; Le 20:24, 26; De 7:3). To intermarry with the heathen would defeat this purpose of Jehovah, who was the common Father of the Israelites in a peculiar sense in which He was not Father of the heathen. The "one Father" is Jehovah (Job 31:15; 1Co 8:6; Eph 4:6). "Created us": not merely physical creation, but "created us" to be His peculiar and chosen people (Ps 102:18; Isa 43:1; 45:8; 60:21; Eph 2:10), [Calvin]. How marked the contrast between the honor here done to the female sex, and the degradation to which Oriental women are generally subjected!

Matthew Henry's Concise Commentary

2:10-17 Corrupt practices are the fruit of corrupt principles; and he who is false to his God, will not be true to his fellow mortals. In contempt of the marriage covenant, which God instituted, the Jews put away the wives they had of their own nation, probably to make room for strange wives. They made their lives bitter to them; yet, in the sight of others, they pretend to be tender of them. Consider she is thy wife; thy own; the nearest relation thou hast in the world. The wife is to be looked on, not as a servant, but as a companion to the husband. There is an oath of God between them, which is not to be trifled with. Man and wife should continue to their lives' end, in holy love and peace. Did not God make one, one Eve for one Adam? Yet God could have made another Eve. Wherefore did he make but one woman for one man? It was that the children might be made a seed to serve him. Husbands and wives must live in the fear of God, that their seed may be a godly seed. The God of Israel saith that he hateth putting away. Those who would be kept from sin, must take heed to their spirits, for there all sin begins. Men will find that their wrong conduct in their families springs from selfishness, which disregards the welfare and happiness of others, when opposed to their own passions and fancies. It is wearisome to God to hear people justify themselves in wicked practices. Those who think God can be a friend to sin, affront him, and deceive themselves. The scoffers said, Where is the God of judgement? but the day of the Lord will come.
