'Three' in the Bible

And there were born unto him seven sons and three daughters.

His substance also was seven thousand sheep, and three thousand camels, and five hundred yoke of oxen, and five hundred she-asses, and a very great household; so that this man was the greatest of all the children of the east.

And his sons went and held a feast in the house of each one upon his day; and they sent and called for their three sisters to eat and to drink with them.

While he was yet speaking, there came also another, and said, The Chaldeans made three bands, and fell upon the camels, and have taken them away, yea, and slain the servants with the edge of the sword; and I only am escaped alone to tell thee.

Now when Job's three friends heard of all this evil that was come upon him, they came every one from his own place: Eliphaz the Temanite, and Bildad the Shuhite, and Zophar the Naamathite, and they made an appointment together to come to bemoan him and to comfort him.

So these three men ceased to answer Job, because he was righteous in his own eyes.

Also against his three friends was his wrath kindled, because they had found no answer, and yet had condemned Job.

And when Elihu saw that there was no answer in the mouth of these three men, his wrath was kindled.

He had also seven sons and three daughters.
