They can be considered heavy burdens to those who are entrusted
Moses, who heard all the greedy Israelites weeping for meat
(Num. 11:4, 34)
Felt that the Lord had been so hard on him
By laying the heavy burden of the Israelites on him (vv. 11, 14)
So that he could carry them in his bosom to the land
Which the Lord swore to their fathers (v. 12).
Since Moses alone wasn’t able to carry all the Israelites,
Because it was too burdensome for him
He asked the Lord to kill him at once
So that he might not see his wretchedness (vv. 14-15).
The people whom the Lord entrusted to us can be too burdensome to us
When they mix up with greedy people in this world (v. 4)
And keep on complaining and weeping (vv. 5-6).
At that time, we can try to evade our responsibilities
Since we cannot afford them anymore.
