The first occurrence.
And he waited yet another seven days; and sent forth the dove; which returned not again to him any more. Gen 8:12
The primitive root.
Strong’s H3176 יחל yachal, a primitive root meaning, “to hope.” The 3-letter root is yud + chet + lamed.
yud י = the closed hand, thus work, throw, worship
chet ח = the wall, thus outside, divide, half
lamed ל = the shepherd’s staff, thus teach, yoke, to, bind
The story: To work (yud) outside (chet) with the staff (lamed), i.e., to work as a shepherd caring for sheep, or to work as a farmer, for the staff also symbolizes the yoke of oxen who draw the plow. Why do men spend their labor in the field or pasture? They have an expectation of a return or profit. But that profit is not immediate, therefore his labor is an investment.
For we were saved in this hope, but hope that is seen is not hope; for why does one still hope for what he sees? But if we hope for what we do not see, we eagerly wait for it with perseverance. Rom 8:24-25
