Genesis 6:4

4 Now giants were upon the earth in those days. For after the sons of God went in to the daughters of men, and they conceived, these became the powerful ones of ancient times, men of renown. ^{▼▼6:4The giants were perhaps those who were giants in their mental stature, not so much in their physical stature. There may also have been stark differences in the physical characteristics of different groups of people, due to small gene pools, in groups separated by tribe or lineage. Some groups may have been markedly larger or stronger than others. The sons of the sons of God and the daughters of men were mighty because God blesses the offspring of those who are holy.(Conte)
,} ^{▼▼6:4 Giants: It is likely the generality of men before the flood were of a gigantic stature in comparison with what men now are. But these here spoken of are called giants, as being not only tall in stature, but violent and savage in their dispositions, and mere monsters of cruelty and lust.(Challoner)}
