'Lean on the Lord' in the Bible

I hate those who pay regard to vain (empty, worthless) idols;But I trust in the Lord [and rely on Him with unwavering confidence].

O house of Aaron, trust in the Lord;He is their help and their shield.

You who [reverently] fear the Lord, trust in Lord;He is their help and their shield.

It will come to pass in that day that the remnant of Israel, and those who have escaped from the house of Jacob will no more again lean on him who struck them, but shall lean on the LORD, the Holy One of Israel, in truth.

Her leaders pronounce judgment for a bribe,Her priests teach for a fee,And her prophets foretell for money;Yet they lean on the Lord, saying,“Is not the Lord among us?No tragedy or distress will come on us.”
