'Seven' in the Bible

Seven sons and three daughters were born to him.

So they sat down on the ground with Job for seven days and seven nights and no one spoke a word to him, for they saw that his pain was very great.

“He will rescue you from six troubles;Even in seven, evil will not touch you.

Now therefore, take for yourselves seven bulls and seven rams, and go to My servant Job, and offer up a burnt offering for yourselves, and My servant Job will pray for you. For I will accept him [and his prayer] so that I may not deal with you according to your folly, because you have not spoken of Me the thing that is right, as My servant Job has.”

He had seven sons and three daughters.
