They bind heavy burdens ... - This phrase is derived from the custom of loading animals. The load or burden is bound up and then laid on the beast. So the Pharisees appointed weighty burdens, or grievous and heavy precepts, and insisted that the people should obey them, though they lent no assistance. The “heavy burdens” refer not here to the traditions and foolish customs of the Pharisees, for Jesus would not command the people to observe them; but they clearly mean the ceremonies and rights appointed by Moses, which Peter says neither “they nor their fathers were able to bear,” Acts 15:10. Those rites were numerous, expensive, requiring much time, much property, and laborious. The Pharisees were rigid in requiring that all the people should pay the taxes, give of their property, comply with every part of the law with the utmost rigor, yet they indulged themselves, and bore as little of the expense and trouble as possible; so that, where they could avoid it, they would not lend the least aid to the people in the toils and expense of their religious rites.
With one of their fingers - In the least degree. They will not render the least aid.
