'Second' in the Bible

He had two wives, the first named Hannah and the second Peninnah. Peninnah had children, but Hannah was childless.

Now the name of his firstborn was Joel; and the name of his second, Abiah: they were judges in Beersheba.

And Saul and the people spared Agag, and the best of the sheep and oxen, and beasts of the second bearing, and the lambs, and all that was good, and would not devote them to destruction; but everything that was mean and weak, that they destroyed utterly.

The three oldest sons of Jesse followed Saul into battle. The names of his three sons who went to the battle were his firstborn Eliab, Abinadab, his second son, and Shammah, the third.

“I’ll give her to him,” Saul thought. “She’ll be a trap for him, and the hand of the Philistines will be against him.” So Saul said to David a second time, “You can now be my son-in-law.”

And it came to pass on the morrow, which was the second day of the month, that David's place was empty: and Saul said unto Jonathan his son, Wherefore cometh not the son of Jesse to meat, neither yesterday, nor to day?

So Jonathan arose from the table in fierce anger, and did eat no meat the second day of the month: for he was grieved for David, because his father had done him shame.

saying, “Don’t be afraid, for my father Saul will never lay a hand on you. You yourself will be king over Israel, and I’ll be your second-in-command. Even my father Saul knows it is true.”

Then said Abishai to David, God hath delivered thine enemy into thine hand this day: now therefore let me smite him, I pray thee, with the spear even to the earth at once, and I will not smite him the second time.
