Sure, the scriptures you posted are from the sermon on the mount. Scroll down at the link below and look for the section about "Do Not Worry".

Gota run for now. :-)
Ah, now I understand. The heading, "Do Not Worry" is in the New King James version. What I posted is from the King James version, which does not have headings for the verses. In fact, Matthew 5-7 doesn't even contain the word "worry."
