Parallel
1 Samuel 2:3
Brenton's English Septuagint · Berean Standard Bible
Boast not, and utter not high things; let not high-sounding words come out of your mouth, for the Lord [is] a God of knowledge, and God prepares his own designs.
Do not boast so proudly, or let arrogance come from your mouth, for the LORD is a God who knows, and by Him actions are weighed.
