'Basis' in the Bible

Everyone kept on bringing gifts on an annual basis, including items made of silver and gold, garments, myrrh, spices, horses, and mules.

Then Ben-hadad said to him, “I restore to you the cities that my father took from your father, and you may set up marketplaces for yourself in Damascus, like my father set up in Samaria.”Ahab responded, “On the basis of this treaty, I release you.” So he made a treaty with him and released him.
