John Wesley on Ezra 3:13

Could not discern - The mixture of sorrow and joy here, is a representation of this world. In heaven all are singing and none sighing; in hell all are wailing, and none rejoicing: but here on earth we can scarce discern the shouts of joy from the noise of the weeping, let us learn to rejoice with them that rejoice, and weep with them that weep. Meantime let us ourselves rejoice as though we rejoiced not, and weep as though we wept not.
