'One' in the Bible

“Oh that there were one among you who would shut the gates, that you might not uselessly kindle fire on My altar! I am not pleased with you,” says the Lord of hosts, “nor will I accept an offering from you.

“My covenant with him was one of life and peace, and I gave them to him as an object of reverence; so he revered Me and stood in awe of My name.

“Do we not all have one father? Has not one God created us? Why do we deal treacherously each against his brother so as to profane the covenant of our fathers?

But not one has done so who has a remnant of the Spirit. And what did that one do while he was seeking a godly offspring? Take heed then to your spirit, and let no one deal treacherously against the wife of your youth.

Then those who feared the Lord spoke to one another, and the Lord gave attention and heard it, and a book of remembrance was written before Him for those who fear the Lord and who esteem His name.

So you will again distinguish between the righteous and the wicked, between one who serves God and one who does not serve Him.
