'Enthusiasm' in the Bible

He will rouse his strength and enthusiasm against the king of the south with a large army. The king of the south will wage war with a large and very powerful army, but he will not be able to prevail because of the plans devised against him.

He had been instructed in the way of the Lord, and with great enthusiasm he spoke and taught accurately the facts about Jesus, although he knew only the baptism of John.

Obey with enthusiasm, as though serving the Lord and not people,

Whatever you are doing, work at it with enthusiasm, as to the Lord and not for people,
