She knelt down and prayed.
Literal
She [topic-は] knelt [and-て] prayed.
祈る ('to pray') is the everyday verb for praying — used both for formal worship and casual hopes ('praying for good weather'). The te-form here sequences two actions: kneel, then pray. Compared with the more elaborate 祈りをささげる ('offer up a prayer'), bare 祈った describes the act simply and without ceremonial framing — more meditative than ritual.
