'Leader' in the Bible

'From the day that I brought my people out of the land of Egypt I did not choose a city among all the tribes of Israel to build a house in order for my name [to be] there. Nor did I choose a man to be leader over my people Israel.

Then they brought the offerings and tithes and holy objects faithfully. And over them [as] leader [was] Conaniah the Levite. And Shimei his brother [was] second [in rank].

And Jehiel, Azaziah, Nathan, Asahel, Jerimoth, Jozabad, Eliel, Ismachiah, Mahath, and Benaiah [were] chief officers under the hand of Conaniah and Shimei, his brother, by appointment of King Hezekiah. And Azaraiah [was] leader of the house of God.
