King James Version

Isaiah 47:8

Therefore hear now this, thou that art given to pleasures, that dwellest carelessly, that sayest in thine heart, I am, and none else beside me; I shall not sit as a widow, neither shall I know the loss of children:

Ezekiel 39:6

And I will send a fire on Magog, and among them that dwell carelessly in the isles: and they shall know that I am the LORD.

Zephaniah 2:15

This is the rejoicing city that dwelt carelessly, that said in her heart, I am, and there is none beside me: how is she become a desolation, a place for beasts to lie down in! every one that passeth by her shall hiss, and wag his hand.

Apostolic Fathers

2 Clement 1:1

Brethren, it is fitting that you should think of Jesus Christ as of God,—as the Judge of the living and the dead. And it does not become us to think lightly of our salvation; for if we think little of Him, we shall also hope but to obtain little [from Him]. And those of us who hear carelessly of these things, as if they were of small importance, commit sin, not knowing whence we have been called, and by whom, and to what place, and how much Jesus Christ submitted to suffer for our sakes. What return, then, shall we make to Him? or what fruit that shall be worthy of that which He has given to us? For, indeed, how great are the benefits which we owe to Him! He has graciously given us light; as a Father, He has called us sons; He has saved us when we were ready to perish. What praise, then, shall we give to Him, or what return shall we make for the things which we have received? We were deficient in understanding, worshipping stones and wood, and gold, and silver, and brass, the works of mens hands; and our whole life was nothing else than death. Involved in blindness, and with such darkness before our eyes, we have received sight, and through His will have laid aside that cloud by which we were enveloped. For He had compassion on us, and mercifully saved us, observing the many errors in which we were entangled, as well as the destruction to which we were exposed, and that we had no hope of salvation except it came to us from Him. For He called us when we were not, and willed that out of nothing we should attain a real existence.

OT Pseudepigrapha

The Letter of Aristeas 2:6

They are written in the Hebrew characters and language and have been carelessly interpreted, and do not represent the original text as I am informed by those who know; for they have never had a king's care to protect them.
