Charles Ellicott Commentary 2 Samuel 12:5

"And David`s anger was greatly kindled against the man; and he said to Nathan, As Jehovah liveth, the man that hath done this is worthy to die:" — 2 Samuel 12:5 (ASV)

Was greatly kindled. —David’s generous impulses had not been extinguished by his sin, nor his warm sense of justice; his naturally quick temper (1 Samuel 25:13; 1 Samuel 25:22; 1 Samuel 25:33) at once roused his indignation to the utmost.
