Targum zu Bereschit 15:1

After these words, when the kings had gathered together, and had fallen before Abram; and four kings had been slain, and nine hosts brought back, Abram reasoned in his heart, and said, Woe to me, because I have received the reward of my appointments in this world, and have no portion in the world to come. Or peradventure the brethren and friends of those who have been slain will combine in legions and come against me; or that at that time there was found with me the reward of a little righteousness, so that they fell before me; but the second time reward may not be found with me, and by me the name of the Heavens may be profaned. Thereupon was the word (pithgama) of the Lord with Abram in a vision, saying, Fear not; for if these men should gather together in legions and come against thee, My Word (Memra) will be thy shield: and also if these fall before thee in this world, the reward of thy good works shall be kept, and be prepared before Me in the world to come, great exceedingly.

After these words, when all the kings of the lands, and the sultans of the provinces, had gathered together, and had made war against Abram the Just, and had fallen before him, and he had slain of them four kings, and had brought back nine hosts, did Abram the Just reason in his heart, and say, Woe, now, to me, because I have received the reward ordained in the present world, and have no portion in the world to come. Or peradventure the brethren and kindred of the slain who have fallen before me, who are in their cities and provinces, will combine in great legions, and come against me; or peradventure there were in my hand a few commandments in the former times, so that they fell before me when they had risen up against me; or it may be that righteousness was found in me at the former times, that they fell before me, but at the second time it may not be found, and the Heavenly Name will be profaned in me. Then was the word of prophecy from the Lord unto Abram the Righteous, saying, Fear not, Abram, though they should gather together and come against thee with many legions, My Word shall be thy reward and thy shield in this world, and a protector over thee all the days of the world to come. And though I deliver up thy adversaries before thee in this world, the reward of thy good works is prepared for thee also before Me in the world to come.
