1At Sāvatthī. "Bhikkhus, whatever Arahants, Perfectly Enlightened Ones, in the past fully awakened to things as they really are, all fully awakened to the Four Noble Truths as they really are. sn.v.434

Whatever Arahants, Perfectly Enlightened Ones, in the future will fully awaken to things as they really are, all will fully awaken to the Four Noble Truths as they really are.

Whatever Arahants, Perfectly Enlightened Ones, at present have fully awakened to things as they really are, all have fully awakened to the Four Noble Truths as they really are.

2"What four? The noble truth of suffering, the noble truth of the origin of suffering, the noble truth of the cessation of suffering, the noble truth of the way leading to the cessation of suffering.

Whatever Arahants, Perfectly Enlightened Ones, fully awakened … will fully awaken … have fully awakened to things as they really are, all have fully awakened to these Four Noble Truths as they really are.

3"Therefore, bhikkhus, an exertion should be made to understand: ‘This is suffering.’[n.376] Tasmātiha bhikkhave idaṁ dukkhan ti yogo karaṇīyo. Spk: Since a concentrated bhikkhu understands the Four Noble Truths as they really are, therefore you should make an exertion to become concentrated in order to understand the four truths as they really are. And since the round of existence increases for those who do not penetrate them, but stops increasing from the time they are penetrated, therefore you should make an exertion to understand them, thinking, "Let the round not increase for us."
An exertion should be made to understand: ‘This is the origin of suffering.’
An exertion should be made to understand: ‘This is the cessation of suffering.’
An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’"
