Yossi Feintuch: Isaac's blessings to Jacob and Esau focus on produce, not on animals

in the he classical Levitical text on a gift (mincha) to God (Ch.2) the plant-based tribute serves not only as alternative to animal offerings, but even as superior to the latter. Notably, Isaac does erect an altar for God in Beersheba, but like in the  majority of altar-building by his father Abraham, no animals are slain there (Genesis 26:25).

Yossi Feintuch: Animals' standing and role in creation is reflected in Noah's Ark

Inundating the earth would also bring devastation to all land and winged animals, none of which was deemed “evil” or “bad’’, like man proved himself to be, and thus, the very reason for the flood. Ergo, God charges Noah – a “righteous and above-reproach-man” – with building a gigantic ark for the preservation of every such species.
