'Solemnly' in the Bible

"Nonetheless they grew disobedient and rebelled against you; they disregarded your law. They killed your prophets who had solemnly admonished them in order to cause them to return to you. They committed atrocious blasphemies.

And you solemnly admonished them in order to return them to your law, but they behaved presumptuously and did not obey your commandments. They sinned against your ordinances -- those by which an individual, if he obeys them, will live. They boldly turned from you; they rebelled and did not obey.

You prolonged your kindness with them for many years, and you solemnly admonished them by your Spirit through your prophets. Still they paid no attention, so you delivered them into the hands of the neighboring peoples.

Our kings, our leaders, our priests, and our ancestors have not kept your law. They have not paid attention to your commandments or your testimonies by which you have solemnly admonished them.
