'Happy' in the Bible

The people of Judah and Israel were as innumerable as the sand on the seashore; they had plenty to eat and drink and were happy.

When Hiram heard Solomon's message, he was very happy. He said, "The Lord is worthy of praise today because he has given David a wise son to rule over this great nation."

On the fifteenth day after the festival started, he dismissed the people. They asked God to empower the king and then went to their homes, happy and content because of all the good the Lord had done for his servant David and his people Israel.

Hiram came out from Tyre to see the cities that Solomon had given him, but he wasn't happy with them,

Happy are thy men, happy are these thy servants, which stand continually before thee, and that hear thy wisdom.

Then his wife Jezebel said to him, “Now, exercise your royal power over Israel. Get up, eat some food, and be happy. For I will give you the vineyard of Naboth the Jezreelite.”
