JMNT(i)
28 "Yet if I, Myself, in union with God's Spirit ([being] within the midst of the effect of God's breath; in an attitude which is God) am constantly driving (or: casting) out the demons, God's reign (the kingdom from God, the sovereign rule which is God, and the government of God) has consequently preceded and come beforehand upon you people (or: has really overtaken you folks and is now arrived and settled upon you).
29 "Or, how does anyone have power or ability to enter into the house belonging to a strong person and to seize (snatch up and plunder) his movable goods (equipment; utensils; gear; belongings; possessions), unless he can (or: should) first bind (tie up) the strong person? After that he will proceed in completely plundering (thoroughly looting) his house.
