'Profaning' in the Bible

Didn't your fathers do thus, and didn't our God bring all this evil on us, and on this city? Yet you bring more wrath on Israel by profaning the Sabbath."

Blessed is the man who does this, and the son of man who holds it fast; who keeps the Sabbath from profaning it, and keeps his hand from doing any evil."

Also the foreigners who join themselves to Yahweh, to minister to him, and to love the name of Yahweh, to be his servants, everyone who keeps the Sabbath from profaning it, and holds fast my covenant;

Don't we all have one father? Hasn't one God created us? Why do we deal treacherously every man against his brother, profaning the covenant of our fathers?
