'Command' in the Bible

For indeed, the LORD is giving the command and he will smash the large house to rubble and the small house into bits.

And though they hide themselves in the top of Carmel, I will search and take them out thence; and though they be hid from my sight in the bottom of the sea, thence will I command the serpent, and he shall bite them:

And though they go into captivity before their enemies, thence will I command the sword, and it shall slay them: and I will set mine eyes upon them for evil, and not for good.

For, lo, I will command, and I will sift the house of Israel among all nations, like as corn is sifted in a sieve, yet shall not the least grain fall upon the earth.
