'Inquired of the Lord' in the Bible

And it came to pass after this, that David inquired of the LORD, saying, Shall I go up into any of the cities of Judah? And the LORD said unto him, Go up. And David said, Where shall I go up? And he said, Unto Hebron.

And David inquired of the LORD, saying, Shall I go up against the Philistines? will you deliver them into my hand? And the LORD said unto David, Go up: for I will doubtless deliver the Philistines into your hand.

And when David inquired of the LORD, he said, You shall not go up; but go around behind them, and come upon them opposite the mulberry trees.

Then there was a famine in the days of David three years, year after year; and David inquired of the LORD. And the LORD answered, It is for Saul, and for his bloody house, because he slew the Gibeonites.
