'Prayer' in the Bible

In the same way the Spirit [comes to us and] helps us in our weakness. We do not know what prayer to offer or how to offer it as we should, but the Spirit Himself [knows our need and at the right time] intercedes on our behalf with sighs and groanings too deep for words.

Brethren, my heart's desire and prayer to God for Israel is, that they might be saved.

Rejoicing in hope; patient in tribulation; continuing instant in prayer;

Now I urge you, brothers and sisters, through our Lord Jesus Christ and through the love of the Spirit, to join fervently with me in prayer to God on my behalf.
