'Marching' in the Bible

However, all of Israel and Judah [were] loving David, for he was going forth and marching ahead of them.

So Achish called David and said to him, "{As Yahweh lives}, certainly you were honest, and {I am pleased to have you marching with me} in the campaign. For I have not found any wrong in you from the day you came to me until this day, but in the eyes of the rulers, you [are] not good.
