Parallel
2 Kings 20:9
Brenton's English Septuagint · Berean Standard Bible
And Esaias said, This [is] the sign from the Lord, that the Lord will perform the word which he has spoken, the shadow [of the dial] shall advance ten degrees: [or] if it should go back ten degrees [this would also be the sign].
And Isaiah had replied, “This will be a sign to you from the LORD that He will do what He has promised: Would you like the shadow to go forward ten steps, or back ten steps?”
