Charles Spurgeon Commentary Hosea 10:1

"Israel is a luxuriant vine, that putteth forth his fruit: according to the abundance of his fruit he hath multiplied his altars; according to the goodness of their land they have made goodly pillars." — Hosea 10:1 (ASV)

Israel is an empty vine, he bringeth forth fruit unto himself:

Not to his God. It does not matter how much fruit we bear — if it is for self, we are really fruitless. A thing which is good in itself may lose all its goodness because it is stained with a selfish motive. We are to live to God; and we must always be watchful about this; otherwise, we may be doing much, and doing nothing. Israel is an empty vine. He bringeth forth fruit unto himself.

According to the multitude of his fruit he has increased the altars; according to the goodness of his land they have made goodly images.

It is a very sad thing when the more men received from God, the more they sin. But just in proportion as the land of Israel was fat and fertile, in that proportion did they set up altars to false gods and provoke the true God, who had given them these mercies. It is a bad thing when men grow rich and offer sacrifice to their own vanity—when men gather learning and only use it to debate against the simple teachings of God—when just as God blesses, men cease to bless him!
