1 Samuel 18:3-4
"And Jonathan made a covenant with David because he loved him as himself. Jonathan took off the robe he was wearing and gave it to David, along with his tunic, and even his sword, his bow and his belt." (NIV)
Since people in those days did not wear underwear, Jonathan stripped himself naked in front of David. That would be considered extremely unusual behavior (then and now) unless their relationship was physical.
1 Samuel 20:41
"After the boy had gone, David got up from the south side of the stone and bowed down before Jonathan three times, with is face to the ground. Then they kissed each other and wept together - but David wept the most." (NIV)
Other translations have a different ending to the verse:
bullet "...and they kissed one another and wept with one another, until David exceeded." (KJV)
<snip>
The original Hebrew text says that they kissed each other and wept together until David became great. The word which means "great" in this passage is "gadal" in the original Hebrew. The same word is used elsewhere in the Hebrew Scriptures to refer to King Solomon being greater than all other kings. Some theologians interpret "gadal" in this verse as indicating that David had an erection. However, the thoughts of David becoming sexually aroused after kissing Jonathan is too threatening for Bible translators, so they either deleted the ending entirely or created one of their own.
