English Translation - Swami Sivananda
4.5 The Blessed Lord said  Many births of Mine have passed as well as of thine, O Arjuna; I know them all but thou knowest not, O Parantapa (scorcher of foes).


English Translation of Sanskrit Commentary By Sri Shankaracharya's
4.5 O Arjuna, bahuni, many; janmani, lives; me, of Mine; vyatitani, have passed; tava ca, and so have yours. Aham, I; veda know; tani, them; sarvani, all; (but) tvam, you; va vetta, know not, due to your power of understanding being obstructed by righteousness, unrighteousness, etc. However, parantapa, O scorcher of foes; aham, I know, possessing as I do unobstructed power of knowledge, because by nature I am enternal, pure, enlightened and free.
In that case, how, in spite of the absence of righteousness and unrighteousness, can there be any birth for You who are the eternal God?
That is beng answered:
