'Decreed' in the Bible

The Lord has done what He planned;He has accomplished His wordWhich He commanded from days of old.He has demolished without sparing,And He has caused the enemy to rejoice over you;He has exalted the power of your enemies.

(Mem) Whose command was ever fulfilled unless the Lord decreed it?

"Go away! Unclean!" they shouted at them. "Go away! Go away! Don't touch!" When they fled away and wandered, those among the nations decreed, "They cannot live here!"
