'Zealous' in the Bible

Then he said, "I have been very zealous for Yahweh the God of hosts, for the {Israelites} have forsaken your covenant. They have demolished your altars, and they have killed your prophets with the sword. I alone am left over, and they seek to take my life.

He said, "I have been very zealous for Yahweh the God of Hosts, for the {Israelites} have forsaken your covenant, demolished your altars, and killed your prophets with the sword; I alone am left, and they seek to take my life!"

then a throne shall be established in steadfast love, and one shall sit on it in faithfulness, in the tent of David, judging and seeking justice and zealous for righteousness.
