'Understands' in the Bible

All things have been handed over to Me by My Father; and no one fully knows and accurately understands the Son except the Father; and no one fully knows and accurately understands the Father except the Son, and anyone to whom the Son [deliberately] wills to reveal Him.

But the one sown on the good ground—this is one who hears and understands the word, who does bear fruit and yields: some 100, some 60, some 30 times what was sown.”
