Galatians 3:5

ἐπιχορηγῶν. The verb χορηγεῖν acquired its meaning from the function of the χορηγός whose duty it was to supply the members of his chorus with all necessary equipment in the course of their training and performance. As men took pride in the liberal fulfilment of this duty, the word came to denote a liberal supply. The compound ἐπιχορηγεῖν denotes apparently an enhancement of this bounty (2 Corinthians 9:10). δυνάμεις. This word is sometimes applied in the Gospels to visible miracles, but in the language of Paul, as elsewhere, it denotes forces or powers. Here accordingly it refers to the supernatural powers imparted by the Spirit to Christians.
