Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain:
Go to now - `Come now:' to excite attention.
Ye that say - `boasting of the morrow.' Today or tomorrow - as if ye had the free choice of cipher day as a certainty. So 'Aleph (') B, Vulgate. But A, 'Today and tomorrow.'
Such a city - literally, this the city. This city here.
Continue there a year - spend a year. They imply that when this year is out, they purpose settling plans for years to come.
Buy and sell. Their plans are all worldly.
