Anonymous. Samuel and Kings were each one book before the Greek translation split them.
When
Covers roughly 1100 to 1010 BC; compiled later.
What it is
The move from judges to kings: Samuel, then Saul, then the rise of David while Saul is still on the throne.
What to watch for
The request for a king is granted and condemned in the same breath, and the book never resolves that tension.
But the LORD said to Samuel, “Do not consider his appearance or height, for I have rejected him; the LORD does not see as man does. For man sees the outward appearance, but the LORD sees the heart.”1 Samuel 16:7
