The verb means to lay hold on: thence to grasp helpfully or to help. To lay hold in the sense of partaking (1Ti 6:2), carries us back to the primitive meaning of the word according to its composition: to receive instead of, or in return (ἀντὶ), and suggests the old phrase to take up for, espouse the cause of. Wyc., has took up, but probably not in this sense.
Servant (παιδὸς)
Often child, son or daughter, but here servant, in allusion to Isa 41:8. Meyer truthfully says that the theocratic notion of sonship is never expressed by παῖς. See Rev., Act 3:13, Act 3:26; Act 4:27, Act 4:30.
