'Contrary' in the Bible

Balaam replied to the servants of Balak, “Though Balak were to give me his house full of silver and gold, I could not do anything, either small or great, contrary to the command of the Lord my God.

The angel of the Lord said to him, “Why have you struck your donkey these three times? Behold, I have come out as an adversary, because your way was contrary to me.

Then Balak said to Balaam, "What have you done to me? I brought you to curse my enemies, but on the contrary you have only blessed them!"

‘Though Balak were to give me his house full of silver and gold, I could not do anything contrary to the command of the Lord, either good or bad, of my own accord. What the Lord speaks, that I will speak’?
