'With All Your Heart' in the Bible

And on that day Moses took an oath, saying, Truly the land where your feet have been placed will become a heritage for you and your children for ever, because you have been true to the Lord your God with all your heart.

But take diligent heed to do the commandment and the law, which Moses the servant of the LORD charged you, to love the LORD your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul.

And lo, I am going, to-day, in the way of all the earth, and ye have known -- with all your heart, and with all your soul -- that there hath not fallen one thing of all the good things which Jehovah your God hath spoken concerning you; the whole have come to you; there hath not failed of it one thing.
