'Heartily' in the Bible

About that time Jesus exclaimed, "I heartily praise Thee, Father, Lord of Heaven and of earth, that Thou hast hidden these things from sages and men of discernment, and hast unveiled them to babes.

He who has the bride is the bridegroom; and the bridegroom's friend who stands by his side and listens to him, rejoices heartily on account of the bridegroom's happiness. Therefore this joy of mine is now complete.

"Immediately, therefore, I sent to you, and I thank you heartily for having come. That is why all of us are now assembled here in God's presence, to listen to what the Lord has commanded you to say."

Now that, through your obedience to the truth, you have purified your souls for cherishing sincere brotherly love, you must love another heartily and fervently.
