Genesis 4:8

“And Cain talked with Abel, etc.] Or “said”, or “spoke unto” him f259 ; either what the Lord God said to him in the foregoing verses, as Aben Ezra; or he spoke to him in a kind and friendly manner, and thereby got him to take a walk in the field with him. The Vulgate Latin version adds, “let us go abroad”; and the Septuagint and Samaritan versions, “let us go into the field”; not to fight a duel, which Abel doubtless would have declined, had that been declared, but to have some friendly conversation; and there being a large pause here in the Hebrew text, the Jerusalem Targum gives us an account of what passed between them when in the field; “Cain said to Abel his brother, there is no…”

“And Cain talked with Abel his brother--Under the guise of brotherly familiarity, he concealed his premeditated purpose till a convenient time and place occurred for the murder (Jo1 3:12; Jde 1:11).”

“- 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 Cain talked with Abel his brother - The Chaldee paraphrast adds, that Cain, when they were in discourse, maintained there was no judgment to come, and that when Abel spoke in defence of the truth, Cain took that occasion to fall upon him. The scripture tells us the reason wherefore he slew him, because his own works were evil, and his brother's righteous; so that herein he shewed himself to be a child of the devil, as being an enemy to all righteousness. Observe, the first that dies is a saint, the first that went to the grave, went to heaven. God would secure to himself the first fruits, the first born to the dead, that first opened the womb into another world. Genesis 4:9”

“4:8 The effects of the Fall on human relationships are tragically expressed in the first murder. • The word brother is used seven times in 4:2-11, highlighting Cain’s fratricide in the face of familial responsibility.”

“talked: Sa2 3:27, Sa2 13:26-28, Sa2 20:9, Sa2 20:10; Neh 6:2; Psa 36:3, Psa 55:21; Pro 26:24-26; Mic 7:6; Luk 22:48 Cain rose: Sa2 14:6; Job 11:15; Psa 24:3-6, Psa 139:19; Mat 23:35; Luk 11:51; Jo1 3:12-15; Jde 1:11 Genesis 4:9”

“He "said to his brother Abel." What he said is not stated. We may either supply "it," viz., what God had just said to him, which would be grammatically admissible, since is sometimes followed by a simple accusative (Gen 22:3; Gen 44:16), and this accusative has to be supplied from the context (as in Exo 19:25); or we may supply from what follows some such expressions as "let us go into the field," as the lxx, Sam., Jonathan, and others have done. This is also allowable, so that we need not imagine a gap in the text, but may explain the construction as in Gen 3:22-23, by supposing that the writer hastened on to describe the carrying out of what was said, without stopping to set down the words…”
