'During' in the Bible

So Daniel prospered during the reign of Darius and the reign of Cyrus the Persian.

After some years they will form an alliance, and the daughter of the king of the South will go to the king of the North to seal the agreement. She will not retain power, and his strength will not endure. She will be given up, together with her entourage, her father, and the one who supported her during those times.

“In his place a despised person will arise; royal honors will not be given to him, but he will come during a time of peace and seize the kingdom by intrigue.

During a time of peace, he will come into the richest parts of the province and do what his fathers and predecessors never did. He will lavish plunder, loot, and wealth on his followers, and he will make plans against fortified cities, but only for a time.
