New American Standard Bible (NASB)
1 Corinthians 9
25 Everyone who competes in the games exercises self-control in all things. They then do it to receive a perishable wreath, but we an imperishable.
26 Therefore I run in such a way, as not without aim; I box in such a way, as not beating the air;
27 but I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.
1 Corinthians 10
1 For I do not want you to be unaware, brethren, that our fathers were all under the cloud and all passed through the sea;
2 and all were baptized into Moses in the cloud and in the sea;
3 and all ate the same spiritual food;
4 and all drank the same spiritual drink, for they were drinking from a spiritual rock which followed them; and the rock was Christ.
5 Nevertheless, with most of them God was not well-pleased; for they were laid low in the wilderness.
6 Now these things happened as examples for us, so that we would not crave evil things as they also craved.
7 Do not be idolaters, as some of them were; as it is written, "The people sat down to eat and drink, and stood up to play."
8 Nor let us act immorally, as some of them did, and twenty-three thousand fell in one day.
