NET
6 Sow your seed in the morning, and do not stop working until the evening; for you do not know which activity will succeed—whether this one or that one, or whether both will prosper equally.
Darby
6 In the morning sow thy seed, and in the evening withhold not thy hand; for thou knowest not which shall prosper, whether this or that, or whether they both shall be alike good.
KJV
6 In the morning sow thy seed, and in the evening withhold not thine hand: for thou knowest not whether shall prosper, either this or that, or whether they both [shall be] alike good.
