That thou shouldest take it to the bound thereof,.... Either darkness, or rather the light; take it as it were by the hand, and guide and direct its course to its utmost bound. This only the Lord can do and does: he has set a tabernacle for the sun, which goes forth at his command as a strong man to run a race; whose going forth is from the end of the heavens, and his circuit unto the ends of it: in which his course is so steered and directed by the Lord, that he never misses his way or errs from it; but keeps his path exactly, as well as knows its rising and setting, its utmost bounds;and that thou shouldest know the paths [to] the house thereof?
from whence it sets out, and whither it returns; see Ps 19:4.
