Where in the Bible does it say that God will not put us in a situation that you cannot handle?

Perhaps the verse you have in mind is 1 Corinthians 10:13 - No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it.[NKJV]
