'Prayer' in the Bible

Then I gave orders for a time of going without food, there by the river Ahava, so that we might make ourselves low before our God in prayer, requesting from him a straight way for us and for our little ones and for all our substance.

So we fasted and sought our God for this and he responded to our prayer.

Now while Ezra was making his prayer and his statement of wrongdoing, weeping and falling down before the house of God, a very great number of men and women and children out of Israel came together round him: for the people were weeping bitterly.
