They, when they heard it, lifted for when they heard that they lifted, A.V.; O Lord, thou that didst make, or as in margin, thou art he that did make, for Lord, thou art God, which hast made, T.R. and A.
V.; the heaven and the earth for heaven and earth, A.V. With one accord ( ὁμοθυμαδόν) occurs eleven times in the Acts (ten times in the R.T.) and only once elsewhere in the New Testament, viz. in Romans 15:6.

It means "master, owner," in respect of slaves, and "a lord" or "king," whose power over his subjects is similar to that of a master over slaves.
