'Wholeheartedly' in the Bible

"Not one of the men who went up from Egypt, from 20 years old and above, will see the land that I promised to give to their ancestors, that is, to Abraham, Isaac, and Jacob, because none of them followed me wholeheartedly,

except Jephunneh's son Caleb, the Kenizzite, and Nun's son Joshua. They've wholeheartedly followed the LORD.'

except Jephunneh's son Caleb. He will see it and I will give to him and to his descendants the land on which he has walked because he wholeheartedly followed the LORD.'

"Because you didn't serve the LORD your God joyfully and wholeheartedly, despite the abundance of everything you have,

Teach me your ways, LORD, that I may walk in your truth; let me wholeheartedly revere your name.

The arrogant have accused me falsely; but I will observe your precepts wholeheartedly.

Whatever you do, work at it wholeheartedly as though you were doing it for the Lord and not merely for people.
