Who asked Job, "Where were you when I laid the foundations of the earth?"

Answer: The LORD

Speaking from the whirlwind, the LORD challenged Job: "Where were you when I laid the foundations of the earth?"

“Then the LORD answered Job out of the whirlwind and said: “Who is this who obscures My counsel by words without knowledge? Now brace yourself like a man; I will question you, and you shall inform Me. Where were you when I laid the foundations of the earth? Tell Me, if you have understanding.”— Job 38:1-4 (BSB)
