Adam Clarke’s Commentary

Verse 20.   Noah began to be a husbandman] hmdahvyaishhaadamah, A man of the ground, a farmer; by his beginning to be a husbandman we are to understand his recommencing his agricultural operations, which undoubtedly he had carried on for six hundred years before, but this had been interrupted by the flood. And the transaction here mentioned might have occurred many years posterior to the deluge, even after Canaan was born and grown up, for the date of it is not fixed in the text.

The word husband first occurs here, and scarcely appears proper, because it is always applied to man in his married state, as wife is to the woman.  The etymology of the term will at once show its propriety when applied to the head of a family.  Husband, [A.S. husband], is Anglo-Saxon, and simply signifies the bond of the house or family; as by him the family is formed, united, and bound together, which, on his death, is disunited and scattered.

It is on this etymology of the word that we can account for the farmers and petty landholders being called so early as the twelfth century, husbandi, as appears in a statute of David II., king of Scotland: we may therefore safely derive the word from [A.S. hus], a house, and [A.S. bond] from [A.S. binben], to bind or tie; and this etymology appears plainer in the orthography which prevailed in the thirteenth and fourteenth centuries, in which I have often found the word written house-bond; so it is in a MS. Bible before me, written in the fourteenth century.  Junius disputes this etymology, but I think on no just ground.
