4. In 2Ki 20:4, the quickness of God's answer to the prayer is marked, "afore Isaiah had gone out into the middle court, the word of the LORD came to him"; that is, before he had left Hezekiah, or at least when he had just left him, and Hezekiah was in the act of praying after having heard God's message by Isaiah (compare Isa 65:24; Ps 32:5; Da 9:21).
