Isaiah 38:7,8

After Isaiah 38:6; Isaiah 38:2 Kings describes the prophet's prescription for the malady (see on Isaiah 38:21). The account of the sign also is given in a much fuller form there. It was granted at the express request of the king (see Isaiah 38:22), who had not his father's fear of "tempting the Lord" (ch. Isaiah 7:12). Allowed to choose between a "going forward" and a "going backward" of the shadow, he decided for the latter as not so "light" a thing (i.e. less conceivable); when, at Isaiah's intercession, the desired thing happened.
