2 Samuel 15:5

put forth his hand Instead of allowing the people to do him homage as the king's son, he took them by the hand, and saluted them familiarly with a kiss. Cp. ch. 2 Samuel 20:9.

Compare the description of Bolingbroke's behaviour which Shakespeare puts into the mouth of Richard II.:

Ourself and Bushy, Bagot here and Green

Observed his courtship to the common people;

How he did seem to dive into their hearts

With humble and familiar courtesy,

What reverence he did throw away on slaves,

Wooing poor craftsmen with the craft of smiles,

King Richard II., Acts 1. Sc. 4:23.
