Albert Barnes Commentary Isaiah 44:19

"And none calleth to mind, neither is there knowledge nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof; I have roasted flesh and eaten it: and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree?" — Isaiah 44:19 (ASV)

And none considers in his heart - Margin, ‘Sets to.’ He does not place the subject near his heart or mind; he does not think of it.

A similar phrase occurs in Isaiah 46:8: Bring it again to mind. This expression is drawn from the act of placing an object near us to examine it closely. We express the same idea by the phrase ‘looking at a thing,’ or ‘looking at it closely.’

The sense is, they had not attentively and carefully thought about the folly of what they were doing—a sentiment which is as true of all sinners as it was of stupid idolaters.

An abomination - A name that is often given to an idol (2 Kings 11:5; 2 Kings 11:7; 2 Kings 23:13). The meaning is that an idol was abominable and detestable in the sight of a holy God. It was that which he could not endure.

Shall I fall down to the stock of a tree? - Margin, ‘That which comes of.’ The word בוּל bûl properly means “produce, increase,” and here evidently a stock or trunk of wood. So it is in the Chaldee.
