Slack hand

1. Josh. 10: 6
   6 ¶ And the men of Gibeon sent unto Joshua to the camp to Gilgal, saying, Slack not thy hand from thy servants; come up to us quickly, and save us, and help us: for all the kings of the Amorites that dwell in the mountains are gathered together against us.
2. Prov. 10: 4
   4 He becometh poor that dealeth with a slack hand: but the hand of the diligent maketh rich.
3. Jacob 5: 47
   47 But what could I have done more in my vineyard? Have I slackened mine hand, that I have not nourished it? Nay, I have nourished it, and I have digged about it, and I have pruned it, and I have dunged it; and I have stretched forth mine hand almost all the day long, and the end draweth nigh. And it grieveth me that I should hew down all the trees of my vineyard, and cast them into the fire that they should be burned. Who is it that has corrupted my vineyard?
