ליטעראַטור פֿון בית שני אויף בראשית 26:12

[190] Abraham too “plants an acre”  and adopts the hundred in measuring out the plot (Gen. 21:33), and Isaac “finds barley a hundredfold” (Gen. 26:12); and Moses in building the court of the tabernacle takes a hundred cubits in measuring out the distance from east to west (Ex. 27:9).

[268] In this same year, too, is “the hundredfold crop of barley found” (Gen. 26:12) by him who sows the gifts of God to produce an increase of blessings, and thereby increases to the uttermost the number of those who shall deservedly partake of it. But note that the sower generally reaps.
