כִּֽי־אָ֭דָם לְעָמָ֣ל יוּלָּ֑ד וּבְנֵי־רֶ֝֗שֶׁף יַגְבִּ֥יהוּ עֽוּף׃
Empero como las centellas se levantan para volar por el aire, Así el hombre nace para la aflicción.
Rashi on Job
Because man is born for trouble For it is impossible that he should not sin and receive trouble as punishment for sin. He is not like the flying creatures—the angels and spirits—who fly upward, and are not of the earthly creatures (other editions read: fly upward so as not to be among the earthly creatures), over whom the Adversary and temptation rule.
Malbim on Job
The comets are neither messengers of the stars nor portents of doom. God alone governs and man has control over his own actions.
Rashi on Job
flying Heb. רשף, as in (Ps. 76:4), “arrows of (רשפי) a bow.” When the arrow flies, it is called רשפי, an expression of flying. This is what I heard.
