Jubilees 17:17
16 Then Prince Mastema came and said before God: ‘Abraham does indeed love his son Isaac and finds him more pleasing than anyone else. Tell him to offer him as a sacrifice on an altar. Then you will see whether he performs this order and will know whether he is faithful in everything through which you test him.’ 17 Now the Lord was aware that Abraham was faithful in every difficulty which he had told him. For he had tested him through his land and the famine; he had tested him through the wealth of kings; he had tested him again through his wife when she was taken forcibly, and through circumcision; and he had tested him through Ishmael and his servant girl Hagar when he sent them away.
Pirkei Avot 5:3
Mishnah2 [There were] ten generations from Adam to Noah, in order to make known what long-suffering is His; for all those generations kept on provoking Him, until He brought upon them the waters of the flood. [There were] ten generations from Noah to Abraham, in order to make known what long-suffering is His; for all those generations kept on provoking Him, until Abraham, came and received the reward of all of them. 3 With ten trials was Abraham, our father (may he rest in peace), tried, and he withstood them all; to make known how great was the love of Abraham, our father (peace be upon him).
Notes and References
"... If there are seven trials mentioned in Jubilees 17:17, the binding of Isaac (Jubilees 18:1–19) was the eighth and Sarah’s death (Jubilees 19:2) possibly the ninth, although these events are not noted in a context designated as trial. If this were the case, the plea for a place to bury her would be the tenth test ... VanderKam also points to Numbers 14:22, where it is said that the people “have tested me these ten times and have not obeyed my voice.” Abraham was also tested ten times in Rabbinic literature, see Pirkei Avot 5:2; Avot of Rabbi Natan 33; Pirkei Rabbi Eliazar 26. The Rabbinic sources do not agree as to what the trials were ..."
