Midrasz do Samuela II 13:4

R. Juda in the name of Samuel said: "Whoever visits a sick person will be saved from the ffiudgment of Gehenna, as it is said (Pa. 41, 2) Happy is he that careth for the poor (Dal). On the day of evil [ra'a] will the Lord deliver him. Dal. (poor), refers to a sick person, as it is said (Is. 38, 12) From pining sickness (midalla) will He snatch me away; or from the following passage (II Sam. 13, 4) Why O son of the king, art thou thus becoming leaner from day to day? And again ra'ah refers to Gehenna, as it is said (Prov. 16, 4) Everything hath the Lord wrought for its destined end: Yea even the wicked for the day of unhappiness (ra'ah). But if one does visit [a sick person] what will be his reward? Why his reward will be as we said before; he will be saved from Gehenna? We must therefore explain it thus: What will be his reward in this world? Everything mentioned in the following passage (Ps. 41, 3) The Lord will preserve him and keep him alive; he shall be made happy on the earth; and Thou wilt not deliver him unto the revengeful desire of his enemies; i.e., the Lord will preserve him from the evil inclination and keep him alive from agonies; he shall be happy on the earth, that all will honor him; and Thou wilt not deliver him unto the revengeful desires of his enemies. He will happen to meet associates like those of Na'amon, who advised him how to he cured of his leprosy, but he will not chance to meet friends like those who happened to associate with Rehobo'am, who caused the division of the latter's kingdom. We are taught in a Baraitha, R. Simon b. Elazar said: "If the elders tell you to destroy, and the young tell you to build, rather destroy according to the advice of the elders and do not build, because the destruction of the elders equals to building, while the building of the young equals to destruction. An example of this may be brought from the case of Rehabo'am, son of Solomon."
