'Deeply' in the Bible

"When a man divorces his wife, she leaves him and becomes another man's wife, will the first husband return to her again? The land would be deeply polluted, would it not? Since you have committed fornication with many lovers, would you now return to me?" declares the LORD.

"Is Ephraim my dear son? Is he a darling child? Indeed, as often as I've spoken about him, I surely still remember him. Therefore I deeply yearn for him. I'll surely have great compassion on him," declares the LORD.
