'Ahead' in the Bible

Now Gehazi went on ahead of them. He placed the staff on the child's face, but there was no sound or response. When he came back to Elisha he told him, "The child did not wake up."

Now Elisha was sitting in his house with the community leaders. The king sent a messenger on ahead, but before he arrived, Elisha said to the leaders, "Do you realize this assassin intends to cut off my head?" Look, when the messenger arrives, shut the door and lean against it. His master will certainly be right behind him."

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?"
