2 Kings 20:9

20:9 Isaiah replied, “This is your sign from the Lord confirming that the Lord will do what he has said. Do you want the shadow to move ahead ten steps or to go back ten steps?”

tn The Hebrew הָלַךְ (halakh, a perfect), “it has moved ahead,” should be emended to הֲיֵלֵךְ (hayelekh, an imperfect with interrogative he [ה] prefixed), “shall it move ahead.”
