'Insensibility' in the Bible

But Jesus said to them, “Because of your hardness of hearts [your callousness and insensitivity toward your wives and the provision of God] he wrote you this precept.

I do not want you, believers, to be unaware of this mystery [God’s previously hidden plan]—so that you will not be wise in your own opinion—that a partial hardening has [temporarily] happened to Israel [to last] until the full number of the Gentiles has come in;

with darkened understandings, having by reason of the ignorance which is deep-seated in them and the insensibility of their moral nature, no share in the Life which God gives.
