3 Bible Verses about Condolence

Jesus saith to her, "Your brother shall rise again." Martha says to Him, "I know that he will rise again, in the resurrection at the last day." Jesus said to her, "I am the resurrection and the life; he that believes on Me, though he die, yet shall he live;read more.
and whosoever lives and believes on Me shall never die. Do you believe this?" She says to Him, "Yea, Lord; I have believed that Thou art the Christ, the Son of God, He Who was to come into the world." And, saying this, she went away, and called Mary her sister privately, saying, "The Teacher is present, and calleth for you." And she, when she heard it, arose quickly, and went to Him. (Now Jesus had not yet come into the village, but was still in the place where Martha met Him.) The Jews, therefore, who were with her in the house, and were comforting her, seeing Mary, that she rose up quickly and went out, followed her, supposing that she was going to the tomb, to weep there. Mary, therefore, when she came where Jesus was, seeing Him, fell at His feet, saying to Him, "Lord, if Thou hadst been here, my brother would not have died." Jesus, therefore, when He saw her weeping, and the Jews weeping who came with her, groaned in the spirit, and troubled Himself; and He said, "Where have ye laid Him?" They say to Him, "Lord, come and see." Jesus wept.

If ye shall ask anything in My name, I will do it.

But we do not wish you to be ignorant, brethren, concerning those falling asleep, that ye sorrow not even as the rest who have no hope; for, if we believe that Jesus died and rose again, so also those who fell asleep in Jesus will God bring with Him. For this we say to You, in a word of the Lord, that we, the living who remain over to the coming of the Lord, shall in nowise precede those who fell asleep;read more.
because the Lord Himself will descend from Heaven, with a shout, with a voice of an archangel, and with a trumpet of God; and the dead in Christ shall rise first; after that we, the living who are left over, will be caught up together with them in clouds, into the air, to meet the Lord; and so shall we always be with the Lord. So then, comfort one another with these words.
