'Pray' in the Bible

As she continued to pray in the LORD's presence, Eli was watching her mouth.

Samuel said, "Bring all Israel together at Mizpah, and I'll pray to the LORD on your behalf."

Then all the people told Samuel, "Pray to the LORD your God for your servants, so that we don't die, because we made all our sins worse by asking for a king for ourselves."

Now as for me, far be it from me that I should sin against the LORD by ceasing to pray for you. I'll also instruct you in the way that is good and right.
