What does the Bible say about prayer in times of trouble?

The scriptures highlight that prayer is crucial in times of trouble, as seen in the account of Moses during the battle against Amalek. While the Israelites fought in the valley, Moses stood on the hill with his hands raised in prayer. The success of the battle directly correlates to his commitment to pray: when he prayed, Israel prevailed; when he grew weary and his hands fell, Amalek prevailed. This illustrates that prayer is not just a religious duty, but a vital means through which God grants victory and sustenance during trials.
