I looked up Hebrews 11:1 in several different translations of the Bible online, here is the result:
New International Version (NIV):
Now faith is being sure of what we hope for and certain of what we do not see.
New American Standard Bible (NASB):
Now faith is the assurance of things hoped for, the conviction of things not seen.
Amplified Bible (AMP):
Now faith is the assurance (the confirmation, the title deed) of the things [we] hope for, being the proof of things [we] do not see and the conviction of their reality [faith perceiving as real fact what is not revealed to the senses].
New Living Translation (NLT)
Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see.
You can look up more different versions of the Bible
here. It allows you to look up multiple versions (five at a time) at the same time. There are lots more Bibles to look up than the ones I did.
