Ba'al Shem Tov, Vayera 13/בעל שם טוב על התורה·וירא י״ג

1And it was, after these things, that G‑d (Elokim) tested Abraham. (Ibid. 22:1)When a person undergoes a trial, he is in the aspect of lack of consciousness (loses his awareness). This explains the verse: “Elokim tested Abraham.” For [the Divine Name] Elokim corresponds to constricted consciousness, as is known. Then, “Elokim tested Abraham,” when the latter was in a state of “smallness.”Teshuos Chen, Likutim on parashas Vayechi
