The reading was Amos 5:6-7, 10-15, and I noticed a small feature that I'd missed earlier that week when the same reading was on Worship Anew.
Here's Amos 5:12: "For I know how many are your transgressions and how great are your sins - you who afflict the righteous, who take a bribe, and turn aside the needy in the gate."
There's parallelism between "how many are your transgressions" and "how great are your sins," and this provides a sense of that large amount.
For what it's worth: I noticed a similar feature in Psalm 49:6 earlier this year.
