Genesis 4:11

“And now [art] thou cursed from the earth, etc.] From receiving benefit by it, and enjoying the fruits of it as before, and from having a settled dwelling in it, as is afterwards explained: which hath opened her mouth to receive thy brother’s blood from thy hand; the blood of his brother, which was shed by his own hand, was received and sucked into the earth, where it was spilt, through the pores of it, and drank up and covered, so as not to be seen; in which it was as it were more humane to Abel, and as it were more ashamed of the crime, and shuddered more, and expressed more horror at it, than Cain.”

“now art thou cursed from the earth--a curse superadded to the general one denounced on the ground for Adam's sin.”

“- Section IV - The Family of Adam - Cain and Abel 1. קין qayı̂n, Qain (Cain), “spear-shaft,” and קנה qānah, “set up, establish, gain, buy,” contain the biliteral root קן qan, “set up, erect, gain.” The relations of root words are not confined to the narrow rules of our common etymology, but really extend to such instinctive usages as the unlettered speaker will invent or employ. A full examination of the Hebrew tongue leads to the conclusion that a biliteral root lies at the base of many of those triliterals that consist of two firm consonants and a third weaker one varying in itself and its position. Thus, יטב yāṭab and טיב ṭôb. So קין qayı̂n and קנה qānah grow from one root. 2. הבל…”

“And now art thou cursed from the earth - 1. He is cursed, separated to all evil, laid under the wrath of God, as it is revealed from heaven against all ungodliness and unrighteousness of men. 2. He is cursed from the earth. Thence the cry came up to God, thence the curse came up to Cain. God could have taken vengeance by an immediate stroke from heaven: but he chose to make the earth the avenger of blood; to continue him upon the earth, and not presently to cut him off; and yet to make even that his curse. That part of it which fell to his share, and which he had the occupation of, was made unfruitful, by the blood of Abel. Besides, A fugitive and a vagabond shalt thou be in the earth. By…”

“4:11-12 As with his father (cp. 3:9-12, 17-19), Cain’s interrogation (4:9-10) was followed by God’s verdict. Adam’s sin had already caused the ground to be cursed. Now Cain was cursed and banished from the land he farmed because he had contaminated it with innocent blood. • homeless wanderer: Cain was condemned to ceaseless roving in a land that would provide neither sustenance nor security. The effects of sin were escalating.”

“Gen 4:14, Gen 3:14; Deu 27:16-26, Deu 28:15-20, Deu 29:19-21; Gal 3:10 opened: Job 16:18, Job 31:38-40; Isa 26:21; Rev 12:16 Genesis 4:12”

“"And now (sc., because thou hast done this) be cursed from the earth." From: i.e., either away from the earth, driven forth so that it shall no longer afford a quiet resting-place (Gerlach, Delitzsch, etc.), or out of the earth, through its withdrawing its strength, and thus securing the fulfilment of perpetual wandering (Baumgarten, etc.). It is difficult to choose between the two; but the clause, "which hath opened her mouth," etc. seems rather to favour the latter. Because the earth has been compelled to drink innocent blood, it rebels against the murderer, and when he tills it, withdraws its strength, so that the soil yields no produce; just as the land of Canaan is said to have spued…”
