Hebrews 2:18

For because he himself has suffered when tempted, he is able to help those who are being tempted.
(Hebrews 2:18 ESV)

The word tempted takes on more of the meaning as put to the proof to see whether a person has sincere piety and love to God. We also see that Jesus showed he had a strength of virtue where no matter what came his way he could bear it. Jesus is qualified to sympathize with us because he has endured like trials. But, he suffered more than we could ever suffer. For that he is our brother and is never ashamed to call us brethren, we can rest our burdens on him.
