“But the tithing system did not originate with the Hebrews. From the earliest times the Lord named the tithe as His; and this claim was recognized and honored. Abraham paid tithe to Melchizedec, the priest of the Most High God. Jacob, when at Bethel, in exile and a wanderer, promised the Lord, ‘of all that Thou shall give me I will surely give a tenth to thee.’ As the Israelites were about to be established as a nation, the law of tithing was reaffirmed, as one of the divinely ordained statues upon obedience to which their prosperity depended.” Patriarchs and Prophets, 525.
