'Second' in the Bible

He had two wives; the name of the first [was] Hannah, and the name of the second [was] Peninnah. Now Peninnah had children, but Hannah had no children.

The name of his firstborn son [was] Joel, and the name of his second son [was] Abijah. [They were] judges in Beersheba.

However, Saul and the army spared Agag and the best of the sheep and the cattle and the second [best] of the young fatlings and {all that was valuable}; they were not willing to utterly destroy them. But all the possessions that were despised or worthless, they utterly destroyed.

The three oldest sons of Jesse had gone and {followed} Saul to the battle. The names of his three sons who went to the battle were Eliab the firstborn, his second [oldest] was Abinadab, and the third was Shammah.

And Saul thought, "I will give her to him, so that she may be a snare for him and the hand of [the] Philistines may be against him." So Saul said to David, "For a second [time] you can become my son-in-law today."

{And then} on the next day, the second day of the new moon, that David's place was empty. So Saul asked Jonathan his son, "Why did the son of Jesse not come either yesterday or today to the feast?"

Jonathan got up from the table {enraged}, and did not eat on the second day of the new moon because he was upset about David, because his father had disgraced him.

He said to him, "Do not be afraid, for the hand of my father Saul will not find you. You will be king over Israel, and {I will be second to you}. My father Saul knows [this] also."
