Genesis 18:6
4 Let a little water be brought so that you may all wash your feet and rest under the tree. 5 And let me get a bit of food so that you may refresh yourselves since you have passed by your servant’s home. After that you may be on your way.” “All right,” they replied, “you may do as you say.” 6 So Abraham hurried into the tent and said to Sarah, “Quick! Take three measures of fine flour, knead it, and make bread.” 7 Then Abraham ran to the herd and chose a fine, tender calf, and gave it to a servant, who quickly prepared it. 8 Abraham then took some curds and milk, along with the calf that had been prepared, and placed the food before them. They ate while he was standing near them under a tree.
Matthew 13:33
31 He gave them another parable: “The kingdom of heaven is like a mustard seed that a man took and sowed in his field. 32 It is the smallest of all the seeds, but when it has grown it is the greatest garden plant and becomes a tree, so that the wild birds come and nest in its branches.” 33 He told them another parable: “The kingdom of heaven is like yeast that a woman took and mixed with three measures of flour until all the dough had risen.” 34 Jesus spoke all these things in parables to the crowds; he did not speak to them without a parable. 35 This fulfilled what was spoken by the prophet: “I will open my mouth in parables, I will announce what has been hidden from the foundation of the world.”
Notes and References
"... The name Fortunatianus is well attested in African Christian circles from the third to the fifth century, which fits Jerome’s assertion of his African origin. The year of his birth is unknown, although it was around 300, and we have no information concerning his early life ... The fact that Jerome does not specify the subject of the commentary implies that it is a single work. Jerome’s third and final mention of Fortunatianus is in the preface to his Commentary on Matthew ... 'For long ago as well, Sarah, who bore the figure of the Church, was found to have made three flatbreads, to show the same total of the Trinity.' (compare Genesis 18:6) ..."
