פּירוש אויף עמוס 7:1

Thus... showed me—retribution, that He wished to bring locusts.

at the beginning of the shooting up of the latter growth [Heb. לֶקֶשׁ, an expression of the latter rain (מַלְקוֹש) when the grain shoots up in its stalk.

and behold the latter growth—was growing after the king’s mowings—After they mowed the king’s grains. Before it would shoot up in its stalk, they would mow it [as] young corn (שַׁחַת) to feed the cattle, and so did Jonathan render it: [After] the king’s young corn (שַׁחֲתָא) was mown. This is a mishnaic expression. (Menachoth 10:8) “One may cut young corn (שַׁחַת) and feed the cattle.”
