'Difficulty' in the Bible

He made the wheels of their chariots wobble so that they drove them with difficulty. The Egyptians said, "Let's flee from Israel because the LORD is fighting for them and against us."

The blessing of the LORD establishes wealth, and difficulty does not accompany it.

LORD, my strength and my stronghold, my refuge in a time of difficulty, to you the nations will come, and from the ends of the earth they'll say, "Surely our ancestors inherited deception, things that are worthless, and in which there is no profit."
