'Completely' in the Bible

that God has completely fulfilled this promise to our children by raising up Jesus, as it is also written in the second Psalm, ‘You are My Son; today I have begotten (fathered) You.’

but when Silas and Timothy came down from Macedonia (northern Greece), Paul began devoting himself completely to [preaching] the word, and solemnly testifying to the Jews that Jesus is the Christ (the Messiah, the Anointed).

and there was a young man named Eutychus (“Lucky”) sitting on the window sill. He was sinking into a deep sleep, and as Paul kept on talking longer and longer, he was completely overcome by sleep and fell down from the third story; and he was picked up dead.
