'Loyal' in the Bible

With antiphonal response they sang, praising and glorifying the Lord: "For he is good; his loyal love toward Israel is forever." All the people gave a loud shout as they praised the Lord when the temple of the Lord was established.

In light of the fact that we are loyal to the king, and since it does not seem appropriate to us that the king should sustain damage, we are sending the king this information

and who extended to me loyal love before the king and his counselors, and before all of the mighty officials of the king. I took courage, for the hand of Yahweh my God was upon me, and I gathered leaders from Israel to go up with me.

For we are slaves and in our bondage our God did not forsake us, and he has extended to us loyal love in the presence of the kings of Persia, to give to us deliverance [and] to set up the house of our God, to repair its ruins, and to give us a wall in Judea and Jerusalem.
