'Ruler' in the Bible

And their chief will be of their number; their ruler will come from among themselves; and I will let him be present before me, so that he may come near to me: for who may have strength of heart to come near me? says the Lord.

All the captains of the king of Babylon came in and took their places in the middle doorway of the town, Nergal-shar-ezer, ruler of Sin-magir, the Rabmag, and Nebushazban, the Rab-saris, and all the captains of the king of Babylon.

Then go back to Gedaliah, the son of Ahikam, the son of Shaphan, whom the king of Babylon has made ruler over the towns of Judah, and make your living-place with him among the people; or go wherever it seems right to you to go. So the captain of the armed men gave him food and some money and let him go.

Now when it came to the ears of all the captains of the forces who were in the field, and their men, that the king of Babylon had made Gedaliah, the son of Ahikam, ruler in the land, and had put under his care the men and women and children, all the poorest of the land, those who had not been taken away to Babylon;

Then Ishmael, the son of Nethaniah, and the ten men who were with him, got up, and attacking Gedaliah, the son of Ahikam, the son of Shaphan, with the sword, put to death him whom the king of Babylon had made ruler over the land.

Because of the Chaldaeans: for they were in fear of them because Ishmael, the son of Nethaniah, had put to death Gedaliah, the son of Ahikam, whom the king of Babylon had made ruler over the land.

So that your hearts may not become feeble and full of fear because of the news which will go about in the land; for a story will go about one year, and after that in another year another story, and violent acts in the land, ruler against ruler.
