Genesis 41:47

And the earth (so) brought forth, that every blade made two handsfull in the seven years of plenty, until all the granaries were full.

‘LIKMATZIM’ (HANDFULS). They stored up the grain handful upon handful, fist by fist. This is the language of Rashi.
Onkelos translated it as, “into store houses,” since excavations made in the earth for storage or other purposes are called ‘kmatzim.’ He is hid now in one of ‘hap’chothim’ (the pits), Jonathan translated, “in one of the kumtza.” Similarly, he always translated the term pachath as kamtza, which is related to the expression, He that diggeth ‘gametz’ (a pit), as the letter gimmel serves here as kuph, just as it serves as a kaph in the following verses: Never lacking in ‘hamazeg’ (mingled wine), the word hamazeg being derived from the term, ‘Mas’cha’ (She hath mingled) her wine; ‘v’chano’ which Thy right hand hath planted,. But Ramban explains it as: “And of the garden, etc.” which is like ganoh (garden); ‘vayisachru’ the fountains of the murmuring deep, which is like vayisagru (and they were closed); To their native land (‘m’churatham’); 16:3 (m’chorotayich). Thy origin (‘m’chorothayich’) and thy birth; 16:3 (m’chorotayich). And I will give over (‘v’sikarti’) Egypt. In all of these cases the kaph and the gimmel are alike. The kuph and the kaph are often alike, as in kova and chova, (both meaning “hat”);; 17:5 (chova). ‘tikein’ (he set in order) many proverbs, the word tikein being like the term sichein in the verse, Who has directed (‘sichein’) the spirit of the Eternal? Our Rabbis have said in connection with the term jewelry: tachshitim and takshit. Similarly, it is said, ‘Vayatziku’ (And they set down) the ark of G-d — but Abiathar went up — until all the people hath passed out of the city, and the Targum translates: “And they put down the ark,” thus making vayatziku as vayatzig, just as it is said concerning it, And they brought in the ark of the Eternal, ‘vayatzigu’ (and set it) in its place,, 6:17. the word being derived from the expressions, ‘atziga’ (let me place) with thee, and ‘v’hitzagtiv’ (And I will set him) before thee.

ותעש הארץ, it produced bountiful harvests. We find the root עשה use in the same sense in Leviticus 25,21 when the Torah describes the bountiful harvests preceding the shemittah year in the words ועשת את התבואה לשלוש השנים, “it will produce a harvest sufficient for the three years.”

לקמצים, a single stalk of grain would yield several handfuls of flour.

ותעש הארץ, the earth produced harvests לקמצים, even a single kernel produced many handfuls. [possibly by “kernel” the author refers to a kernel of seed. Ed.]

לקמצים, “in fistfuls.” Joseph’s overseers took a fifth of a fistful, even of the last fistful remaining in the farmer’s barn, as part of the grain to be stored for the future.
