'Seven' in the Bible

He had seven sons and three daughters.

Then they sat on the ground with him seven days and nights, but no one spoke a word to him because they saw that his suffering was very intense.

He will rescue you from six calamities;no harm will touch you in seven.

Now take seven bulls and seven rams, go to My servant Job, and offer a burnt offering for yourselves. Then My servant Job will pray for you. I will surely accept his prayer and not deal with you as your folly deserves. For you have not spoken the truth about Me, as My servant Job has.”

He also had seven sons and three daughters.
