In the course of time, David inquired of the LORD. "Shall I go up to one of the towns of Judah?" he asked. The LORD said, "Go up." David asked, "Where shall I go?" "To Hebron," the LORD answered. 2 Samuel 2:1
Wouldn't it be great if we were to seek God as David did and get answers right away like he did? Even though those were very different times and they used different means to "inquire of the Lord" (through the priests, ephods, Urim, Thummin, and personally), the principle is the same, they still had to humble themselves to ask. I'll take this passage at face value and understand it to mean that David heard from the Lord himself as to what he should do. The Lord answered and David obeyed.
Wise leaders pray. They realize that they don't have all the answers. David didn't have all the answers and he was the King over Judah. As leaders and followers, we can learn this simple lesson, the great men and women of the Bible prayed to God. Sounds simple but when you're in the thick of major issues and policies, prayer goes by the wayside. Prayer then may have looked different than what we know today, but the fact remains: they humbled themselves to ask God to give them wisdom and counsel.
If there's an issue that you're wrestling with, keep wrestling with God over it. I've said it before, the wrestling may be more important than the actual answer! Keep at it; you'll come through, and when you do, God will get the glory!
