Ezra 4:3 - Joseph Benson’s Commentary on the Old and New Testaments

Ye have nothing to do with us The chief of the fathers were soon aware that they meant them no kindness, whatever they might pretend, but really designed to do them an injury; and therefore, (though they had need enough of help, if it had been such as they could confide in,) they told them plainly they could not accept it, nor unite with them, as being of another nation and religion, and therefore not concerned in Cyrus's grant, which was confined to the Israelites. But we ourselves will build For you are none of those with whom we dare hold communion. Thus we ought to take heed with whom we go partners, and on whose hand we lean. While we trust God with an absolute confidence, we must trust men with a prudent caution. They do not plead to them the law of their God, which forbade them to mingle themselves with strangers, though they especially had an eye to that, but they urge what they knew would have greater weight with them, the king's commission, which was directed to themselves only. In doing good we have need of the wisdom of the serpent, as well as of the innocence of the dove.
