베레시트 (창세기) 15:2

הולך ערירי I GO CHILDLESS — Menachem ben Seruk explained it (ערירי) as meaning heir, and another example of it is (Malachi 2:12) ער ועונה “son and grandsonערירי — (״ then would mean “without child or heir” being an example of a word that has two opposite meanings, just as you say (Job 31:12) “and it would תשרש all my increase” — meaning it would tear up its roots, and the same word might also mean to take root. So, too, the meaning of ערירי is “without a child” although ער means “a child”. old French désenfanté; English childless. It, however, seems to me that the word ער in ער ועונה is of the same derivation as the same word in (Song 5:2). ולבי ער “and my heart awaketh”, whereas ערירי has the meaning of destroyed (a childless person being “demolished” so far as his memory in future generations is concerned; cf. Rashi on Genesis 16:2). Similarly (Psalms 137:7) ערו ערו “Rase it, rase it”; (Habakkuk 3:13) ערות יסוד “destroying the foundation”, and (Jeremiah 51:58) ערער תתערער “shall be utterly destroyed” and (Zephaniah 2:14) כי ארזה ערה “for the cedar-work thereof shall be destroyed”. ובן משק ביתי AND THE STEWARD OF MY HOUSE — Explain it as the Targum has it, “the man of my household”, meaning the man by whose orders all my household is fed. Similarly, (Genesis 41:40) “And according to thy word shall all my people be fed (ישק)” — so that it signifies my administrator. If, however, I had a son, my son would be in charge of my affairs. דמשק OF DAMASCUS — According to the Targum he was of Damascus, but according to the Midrashic explanation (Genesis Rabbah 44:9) he bore this designation because he had pursued the kings as far as Damascus. In the Talmud (Yoma 28b) they explained it as an abbreviation of דולה ומשקה “One who drew up and gave to drink to others of the edifying waters of instruction given by his Teacher.

וַיֹּ֣אמֶר אַבְרָ֗ם אֲדֹנָ֤י יֱהֹוִה֙ מַה־תִּתֶּן־לִ֔י וְאָנֹכִ֖י הוֹלֵ֣ךְ עֲרִירִ֑י וּבֶן־מֶ֣שֶׁק בֵּיתִ֔י ה֖וּא דַּמֶּ֥שֶׂק אֱלִיעֶֽזֶר׃

And Avram said, Lord God, what wilt thou give me, seeing I go childless, and the steward of my house is Eli῾ezer of Dammeseq?
