'Securely' in the Bible

And I will clothe him with your tunicAnd tie your sash securely about him.I will entrust him with your authority,And he will become a father to the inhabitants of Jerusalem and to the house of Judah.

“Now, then, hear this, you sensual one,Who dwells securely,Who says in your heart,‘I am, and there is no one besides me.I will not sit as a widow,Nor know loss of children.’
