Albert Barnes Commentary Ecclesiastes 5:1

"Keep thy foot when thou goest to the house of God; for to draw nigh to hear is better than to give the sacrifice of fools: for they know not that they do evil." — Ecclesiastes 5:1 (ASV)

Keep your foot - that is, Give your mind to what you are going to do.

The house of God - It has been said that here an ordinary devout Hebrew writer might have been expected to call it “the house of Yahweh;” but to those who accept this book as the work of Solomon after his fall into idolatry, it will appear a natural sign of the writer’s self-humiliation, an acknowledgment of his unworthiness of the privileges of a son of the covenant, that he avoids the name of the Lord of the covenant (see Ecclesiastes 1:13 note).

Be more ready to hear - Perhaps in the sense that, “to draw near for the purpose of hearing (and obeying) is better than and so on.”
